"*Theory and Phenomenology of Sparticles*", which was
published in 2004 by World Scientific, Singapore; the publisher's web
page of this book can be found here. This
web page contains a list of all mistakes in the book we are aware of
that can distort the content. Mere spelling mistakes (typos) are not
listed. *We are grateful for any mistakes communicated to us,
* preferably by e-mail (to drees@th.physik.uni-bonn.de, or to
rohini@cts.iisc.ernet.in, or to probirrana@gmail.com). We also
include a few important updates, and clarify potentially misleading
statements. The errors and updates are listed below by chapter and
page number.

*The second print of our book has now appeared * (also
available as soft cover). Many typos have been corrected in this
second print, as indicated below.

__ Sparticle and Higgs mass bounds__ (see also Ch.15) (last update:
May 2011):

The Tevatron experiments have by now collected more than 5 fb^{-1} of
data. Unfortunately still no SUSY signal has been observed, leading to improved
mass bounds. A recent summary of sparticle and Higgs boson search limits is
arXiv:0903.0046 [hep-ex], by
J.L. Feng, F. Grivaz and J. Nachtman; this review also contains many references
to the original literature. Some results are:

-) * Charginos and neutralinos*: under the most favorable
circumstances, searches for hadronically quiet 3l events (see Ch.15.2) lead to
a lower bound of about 164 GeV for the masses of the first chargino or second
neutralino. However, if the leptonic BR of the second neutralino is 3.3% (i.e.,
dominated by Z exchange), existing Tevatron data still do not allow to improve
the LEP2 limit of about 104 GeV.

-) * Generic squarks and gluinos*: searches for final states with
N_{j} > 1 jets and large missing E_{T} (see Ch.15.4) exclude
gluino masses below 308 GeV if squarks are heavy. For degenerate squark and
gluino masses, the bound improves to 390 GeV. Within mSUGRA, a lower bound on
the average of the 10 squark masses (not icluding the stop) of about 380 GeV
has been derived.

-) Searches for pairs of * light sbottom squarks * decaying into a
b-jet and a stable neutralino LSP with unit branching ratio lead to a lower
bound on the sbottom mass of about 220 GeV for light neutralino, and still
nearly 200 GeV for an LSP mass of 80 GeV; there is no sensitivity to heavier
LSPs.

-) Seaches for pairs of * light stop squarks * decaying into a
c-jet and a stable neutralino LSP with unit branching ratio lead to a lower
bound on the stop mass of about 150 GeV for LSP mass below 50 GeV; there is no
sensitivity to LSPs heavier than about 70 GeV. Note also that this decay mode
is expected to be subdominant once the stop mass exceeds the sum of W, b and
LSP masses. If instead the light stop decays into a b-jet, a charged lepton and
a (stable or invisibly decaying) sneutrino with unit branching ratio, the stop
mass bound improves to about 186 GeV for sneutrino mass below 70 GeV; there is
no sensitivity to sneutrino masses above 105 GeV. Finally, if stop decays into
a b quark and a chargino, the bound depends on the leptonic branching ratio of
the chargino, extending to 165 (180) GeV if this branching ratio is 25% (50%).

-) Tevatron data do not improve the LEP bounds on the masses
of *sleptons*, except in some specific R-parity violating scenarios
(see below).

-) * GMSB:* Inclusive searches for final states with two hard,
isolated photons and large missing E_{T} lead to mass bounds of about
149 (280) GeV for the mass of the lightest neutralino (chargino) in GMSB models
with prompt decays of a neutralino NLSP (i.e., for sufficiently small gravitino
mass). CDF also searched for similar events where the photons do not point back
to the production vertex, i.e. for relatively late neutralino decays. Lightest
neutralino masses below about 100 GeV can be excluded for lifetimes around 5
ns.

-) Searches for * long-lived charged particles * allow to exclude
sufficiently long-lived wino-like charginos with mass up to 206 GeV. Stable
stops are excluded if their mass is below 249 GeV.

-) * R-parity violation through lambda coupling * (see Ch.15.6):
searches for events with at least three charged leptons lead to a lower bound
of the mass of the neutralino LSP of about 120 GeV in models with explicit
R-parity violation by lambda_{121 or 122}; in case of
lambda_{133} the bound is reduced to about 90 GeV, since tau leptons
are more difficult to detect.

-) * R-parity violation through lambda' coupling*: D0 searched for
single smuon or muon-sneutrino production through the R-parity violating
coupling lambda'_{211}, and placed bounds on the slepton mass of 210,
340 and 363 GeV for coupling strength 0.04, 0.06 and 0.1, respectively.
CDF searched for the pair production of light stops, with each stop decaying
through the R-parity violating coupling lambda'_{333} into a b-jet and
a tau lepton, and puts a lower bound on the stop mass of 155 GeV for unit
branching ratio. Finally, HERA experiments exclude squark masses up to 275 GeV
if the coupling involves first generation leptons and (s)quarks.

-) Searches for * neutral MSSM Higgs bosons * decaying into
tau pairs now significantly extend the LEP2 limits in the region of very large
tan(beta); they have recently been combined
in arXiv:1003.3363 [hep-ex] . For
example, m_{A} > 200 GeV is required for tan(beta) > 54; for
tan(beta) = 40, the region 110 GeV < m_{A} < 180 GeV, as well as the
region near m_{A} = 90 GeV, are excluded. Below
tan(beta) = 30, all values of m_{A} are allowed. In the context of
the MSSM, the bounds derived from searches for * charged Higgs bosons
*produced in top decay are somewhat weaker. Note also that there is now
a publicly available code,
HiggsBounds, which checks whether a parameter point is compatible with
all existing Higgs search limits;see
arXiv:0905.2190 [hep-ph] , by P. Pechtle et al. .

In the last few months, limits from the first 35 pb^{-1} of LHC data,
taken at root-s = 7 TeV, have started to appear. Unfortunately again no clear
signal has been found. Moreover, due to the limited data sample, the LHC limits
should still be taken with a grain of salt: whereas in most channels searched
at the Tevatron there is no great difference between mass bounds at 95% or 99%
confidence level, the latter may no exist at all for LHC data. The reader
should bear in mind that the Standard Model is at any given moment excluded by
several measurements at more than 95% c.l.

With this caveat, here is a summary of **LHC results**:

-) Both CMS
(arXiv:1101.1628 [hep-ex] )
and ATLAS
(arXiv:1102.5290 [hep-ex] )
searched for events with jets and missing E_{T}. ATLAS has better
bounds, since they find fewer events than predicted by backgrounds (this is
true for many of their searches). For direct decays into a massless lightest
neutralino as LSP, equal squark and gluino masses up to about 850 GeV are
excluded. In an mSUGRA framework, squark masses up to about 780 GeV, and gluino
masses up to about 850 GeV are excluded; the bound becomes irrelevant for
m_{0} > 800 GeV. This constraint should be relatively robust against
changes of other model parameters.

-) ATLAS searched for events with at least one b-jet and missing
E_{T}. Gluinos decaying into b squarks are excluded below about 590 GeV
for b squark masses up to 500 GeV, if all b squarks decay into a b quark and a
stable lightest neutralino. Combining final states with zero and one lepton, in
an optimal mSUGRA framework squark and gluino masses up to about 650 GeV are
excluded; the resulting bound on M_{1/2} remains above the LEP limit of
about 160 GeV for m_{0} up to 1100 GeV; see
arXiv:1103.4344 [hep-ex] .

-) ATLAS searched for events with (at least) one lepton, jets and missing
E_{T}. Within an mSUGRA framework with small tan(beta), this excludes
squark masses up to about 850 GeV, and gluino masses up to about 750 GeV; there
is no bound for m_{0} > 750 GeV; see
arXiv:1102.2357
[hep-ex] . ATLAS also searched for events with two charged leptons, jets
and missing E_{T}. For favorable mSUGRA scenarios, squark and gluino
masses up to 650 GeV are excluded at 95% c.l., but there is no bound for
m_{0} > 280 GeV;
see arXiv:1103.6214
[hep-ex] . These bounds depend somewhat on leptonic branching ratios of
charginos and neutralinos.

-) CMS searched for events with a lepton, a photon and missing E_{T}.
This leads to a lower bound of about 450 to 500 GeV on the masses of gluinos
and squarks in GMSB scenarios where the neutralino NLSP decays promptly into a
photon and a gravitino; see
arXiv:1105.3152 [hep-ex] .
In the same framework, a CMS search for events with two photons and missing
E_{T} excludes equal squark and gluino masses up to about 800 GeV; see
arXiv:1103.0953 [hep-ex] .

-) CMS also published first limits on MSSM Higgs bosons, based on searches for
final states containing an oppositely charged tau pair, at least one of which
decayed purely leptonically. They observe slightly fewer events than predicted
from background, and exclude tan(beta) above about (30, 23, 31, 42, 55) for
m_{A} = (100, 150, 200, 250, 300) GeV; see
arXiv:1104.1619 [hep-ex] .

__Notations, Conventions and Basic Superfield Definitions__

\sigma^{\mu\nu } and \bar\sigma^{\mu\nu } are not quite
correct; the correct definitions are given on p.30. Note that in
\sigma^{\mu\nu } the first Pauli matrix is always without bar, the

in the 2^{nd} line of this equation. (1^{st} print only.)

__Chapter 5__

**Page 74**, eq.(5.8a): the ordering of the scalar fields is
inconistent with subsequent equations: we need (\bar{\phi}^i
\phi_i) in front of the squared mass matrix, and (\phi_j
\bar{\phi}^j)^{T} after this matrix. (1^{st} print only.)

**Page 75**, 2^{nd} unnumbered eq.: in the first expression,
W_{k } should be \bar{W}^{k}; in the 2^{nd} expression,
\bar{W}^{k } should be W_{k}. (V and its derivatives
always contains one W and one \bar{W}.) (1^{st} print only.)

**Page 77**, first line: the word 'minus' at the end of the line should be
omitted; moreover, in the beginning of the third line the sign in front of
Im(phi) should be plus, not minus.

**Page 77**, eq.(5.17) and the following unnumbered eq.: eta should
be replaced by 2 eta, for consistency with eq.(5.18) and subsequent
results. Note also that (5.18), and the results derived from it, only
hold in the Wess-Zumino supergauge. (1^{st} print only.)

**Page 85**, eq.(5.47b): \Lambda in both exponents should be
\Lambda^\dagger, i.e. the conjugate, right-chiral superfield should appear
here. (Thanks to Philipp Varso and Alexander Voigt.)

**Page 87**, eq.(5.60): in the second term on the rhs, the sign in front of
g_{s } should be minus rather than plus.

**Page 88**, Fig.5.2: the sign of the last vertex factor, for the gluino
gluino gluon vertex, should be plus rather than minus.

**Page 90**, eq.(5.63): in the second term inside the first square
parentheses, a dot is missing on the first subscript A. (Thanks to Alexander
Voigt.)

**Page 91**, eq.(5.64): in the 3^{rd} term in the 2^{nd}
line, a Dirac matrix \gamma^\mu contracting the covariant derivative is
missing. (Thanks to Alexander Voigt.)

**Page 94**, Fig.5.3, first Feynman rule on this page: the coupling factor
should be g_Y^2, rather than g_2^2.

__Chapter 6__

**Page 120**, first unnumbered eq.: the mass term (m/2) \int
d^{6}z Phi^{2} + h.c., should be added to the
Wess-Zumino action. (1^{st} print only.)

**Page 129**, eq.(6.87c): On both sides of this equation, \lambda should be
replaced by f.

**Page 131**, eq.(6.97): The subscript on the renormalized superfield on the
rhs should be i' rather than i; summation over i' is understood. (1^{st} and 2^{nd}
print only.)

**Page 135**, eq.(6.107): the coefficient of the beta-function
b^{(1)}_{g2} should have an
additional label |_{SUSY}, to distinguish it from the general case
treated in eq.(11.1). (1^{st} print only.)

__Chapter 7__

**Page 144**, first bullet, line 3: "ftnt.1" should be "ftnt.2". (1^{st}
print only.)

**Page 146**, 5th line from the bottom of the page: "asymmetrically
placed" should be "symmetrically placed". (1^{st} print only.)

**Page 148**, l.7: "in the Phi_{2}, Phi_{3}
superfields" should be inserted after "physical states". (1^{st} print only.)

**Page 152**, first paragraph of Sec.7.7: The acronym "SSB" used here for
"SuperSymmetry Breaking", should be replaced by "ESB" for "Explicit
Supersymmetry Breaking", in order to avoid confusion with "Spontaneous
Supersymmetry Breaking", which is abbreviated by "SSB" in other places
(e.g. on p.140). (1^{st} and 2^{nd} print only.)

__Chapter 8__

**Page 171**, (8.31): the third and fourth term should have -g_{s}
in the exponent, for consistency with (5.57b). (Thanks to Amon Ilakovac.) (1^{st}
and 2^{nd} print only.)

**Page 172**, (8.32): only the first term in square parentheses, which
describes the kinetic energies and gauge interactions of the Higgs
superfields, needs to be summed over p. The terms containing the
superpotential should NOT be summed over p. (Thanks to Alexander Voight and
Philipp Varso.)

**Page 173**, (8.35c): the second and third terms on both right hand sides
should come with minus signs, for consistency with (5.57b). (Thanks to Amon
Ilakovac.) (1^{st} and 2^{nd} print only.) Note that (8.45) and (8.49) are correct as
given.

**Page 180**, (8.48): the last $\tilde d$ in the first line should be a
$\tilde u$. (Thanks to Nicki Bornhauser).

__Chapter 9__

**Page 189**, (9.11a,b): there should not be any tildes on the rhs of these
equations; the fields appearing here are the mixed 2-component charginos
introduced in (9.9), and written without tilde. Fields with tilde are
4-component fermions. (Thanks to Philipp Varso and Alexander Voigt.)

**Page 195**, (9.38): in the second line, the first index of the first
mixing matrix {\cal U} of the second term should be m (to match the index of the
chargino on the left), not l. (Thanks to Philipp Varso and Alexander
Voigt.)

**Page 198**, (9.48): The (RR) entry of the sfermion mass matrix should also
come with a square. (Thanks to Nicki Bornhauser.)

**Page 206**, 2^{nd} paragraph, l.13: the quantities $\delta^{\tilde
q}$ should scale like the squark mass divided by 500 GeV, not divided
by 5000 GeV. (Thanks to Sudhir Vempati.) (1^{st} print only.)

**Page 208**, 2 l. below (9.63): "(9.62)" should read "(9.63)". (Thanks
to Rishikesh Vaidya.) (1^{st} and 2^{nd} print only.)

**Page 217**, first line of last paragraph: "ftnt.9" should be
"ftnt.10". (1^{st} print only.)

__Chapter 10__

**Page 219**, eq.(3): a subscript i is missing on the quark doublet
superfield Q (twice).

**Page 221**, eq.(10.10): the power -1 should be -1/2. (Thanks to Josef
Pradler.)

**Page 221**, eq.(10.12): the first term in parentheses on the r.h.s.,
containing the gauge couplings, should not be squared. (1^{st} and 2^{nd} print
only.)

**Page 222**, 3 l. below (10.15): $\mu^2$ should be $|\mu^2|$.

Moreover, the derivation of (10.18) also makes use of (10.9), in addition to
(10.7), (10.10) and (10.17) (1^{st} print only.)

**Page 242**, eq.(10.51b): Since we are only interested in corrections to
Higgs boson masses involving Yukawa couplings, we have neglected
contributions to the stop masses that are proportional to electroweak gauge
couplings.

**Page 243**, 2^{nd} paragraph, line 9: (10.53) should read (10.52).

**Page 243**, eq.(10.58a): In the second line, (M_{Z}^{2} -
m_{A}^{2}) should be (m_{A}^{2} -
M_{Z}^{2}). (Thanks to Christopher McCabe.) Note also that h
is the lighter Higgs boson, H the heavier one.

**Page 245**, eq.(10.61): The difference of squared stop masses under the
square root should be squared. (Thanks to Swarup Kumar Majee.) (1^{st} and 2^{nd}
print only.) Also, as in (10.51b) we have ignored electroweak gauge
contributions to the field dependent stop masses.

**Page 248**, eq.(10.73): Additional 2-loop corrections to m_{h }
have been evaluated by Brignole et al. in hep-ph/0112177, hep-ph/0206101,
which can increase m_{h } by a few GeV. Including theoretical
and parametric uncertainties, and allowing stop masses up to 2 TeV,
Allanach et al. conclude in hep-ph/0406166 that light Higgs masses up
to 152 GeV might be possible in the general MSSM. On the other hand, the
current (summer 2006) central value for the top mass has been reduced to
m_{t }=172.5 GeV [CDF Collab. and D0 Collab., hep-ex/0605106],
leading to correspondingly lower values of m_{h}.

__Chapter 11__

**Page 256**, eq.(11.11): the second term on the right hand side should be
subtracted from, not added to, the first term. Moreover, the factor 2 \pi in
the denominator of this term should be 8 \pi^2.

**Page 259**, unnumbered eqs. above eqs.(11.16): the primes should be on the
left-hand side in both cases; the fields on the right-hand sides should be
without prime. Moreover, in the second equation, the second
\bar{\eta} should be \eta. When applying these transformations, the
supersymmetric part of the Lagrangian should first be written with primed
fields, i.e. the total primed Lagrangian also contains a supersymmetric part
which is identical to that in (11.14a) with all fields replaced by primed
fields. The transformations described by the unnumbered eqs. on p.259 should be
applied to the entire primed Lagrangian. (1^{st} and 2^{nd} print only.)

Eq.(11.16c): the \kappa* \kappa term should come with negative, rather than
positive, sign. (1^{st} and 2^{nd} print only.)

**Page 261**, Fig.11.3: The left vertex in the top-left diagram should also
have coupling {\cal A}, rather than f, this also being a spurion vertex. (1^{st}
and 2^{nd} print only.)

__Chapter 12__

**Page 290**, first equation below the figure: the denominator on
the RHS should be "tan^{2}beta-1", rather than
"tan^{2}beta". (1^{st} print only.)

**Page 308**, eq.(12.56b): note that in our convention, taking all diagonal
MSSM Yukawa couplings to be positive, we have A_{t } =
-A_{ijk}, with i standing for stop_{L }, j standing for
stop_{R }, and k standing for h_{2}^{0} . This
leads to the MSSM expressions listed in Table 12.1.

**Page 310**, table, second row: the Yukawa coupling in front of the
expression in parentheses should be the bottom coupling f_{b}, not the
top coupling f_{t}. (1^{st} and 2^{nd} print only.)

**Page 319**, eq.(12.90d): the coefficient 1/M_{Pl} multiplying the
last two lines of the rhs should be moved inside the curly bracket, i.e. it
should multiply only the first of these three terms. (Thanks to Charanjit
S. Aulakh.) (1^{st} and 2^{nd} print only.)

__Chapter 13__

**Page 325**, 2^{nd} line of eq.(13.8): the second term should read
x^{2}/36, not x^{2}/16. (Thanks to Daisuke Nomura.)

**Page 328**, Table 13.1: The phase space factors in the expressions for the
partial widths for neutralino to gravitino plus massive boson decays should be
raised to the fourth power. Moreover, N_{i3} should be replaced by
Z_{i4}, and N_{i4} by Z_{i3}, Z being the neutralino
mixing matrix defined in Sec.9.2. Finally, in the expression for the partial
width for the A plus Gravitino mode, the relative sign between the two terms in
the absolute square should be plus, not minus. (Thanks to Steve Martin.) (1^{st}
and 2^{nd} print only.)

__Chapter 14__

**Page 344**, 1^{st} paragraph, l.15: "16.4" should be "16.5". (Thanks
to Rishikesh Vaidya). (1^{st} and 2^{nd} print only.)

**Page 360**, last paragraph: the discussion in the first nine lines of
this paragraph is misleading. First of all, the phrases "baryon parity" and
"lepton parity" in line 2 should be replaced by "baryon number" and "lepton
number". Second, the sentences in lines 5-9 beginning with "A systematic
....." and ending with "...this virtue." should be replaced by the
following:

"A systematic analysis of all Z_{N } symmetries revealed [14.39]
that the only discrete symmetries, permitted by the anomaly free condition,
are the usual Z_{2 }matter parity (corresponding to standard R-parity,
cf. Sec. 4.5) and a Z_{3 } symmetry which has been called 'generalized
baryon parity'. The latter forbids the baryon number violating term in the
superpotential (14.14) but allows the lepton number violating ones. Indeed, an
invariance under this 'generalized baryon parity' does prohibit certain
dimension five operators which are embarassing for GUT-induced proton
decay. Therefore 'generalized baryon parity' is preferred over matter parity
which does not have this virtue." (Thanks to Marc Thormeier.) (1^{st}
and 2^{nd} print only.)

**Page 347**, eq.(14.2): in the first line, h^{0}_{2} should
be h_{2}, i.e. the doublet is meant here, not only its neutral
component. (Thanks to Alexander Voigt.)

**Page 376**, eq.(14.43a): the rhs should have a minus sign in
front. (1^{st} and 2^{nd} print only.)

__Chapter 15__

**Page 391**, first line: the components Z_{n1}, Z_{n2},
Z_{l1} and Z_{l2}, which are in fact gaugino components, should
be replaced by the higgsino components Z_{n3}, Z_{n4},
Z_{l3} and Z_{l4}. (Thanks to Arindam Chatterjee.)

**Page 398**, Fig.15.7: in the last (bottom-right) Feynman diagram a label
"\tilde f^\prime" should be added in parentheses to the exchanged sfermion
line. (Thanks to Sascha Bornhauser.)

**Page 403**, Fig.15.9: The "Run II" region is a 99% c.l. exclusion
region. A true discovery (with at least five standard deviations
statistical significance) would require more than 2 fb^{-1} of
data in the depicted region of parameter space. See [15.5] for further
details.

**Page 405**, unnumbered eq. for the maximal di-lepton invariant mass: the
first factor should be the mass of the decaying heavier neutralino_{2},
rather than that of the lightest neutralino_{1}. (Thanks to Steve
Martin.)

__Chapter 16__

**Page 455**, line 6: "should" should be deleted. (1^{st} print only.)

**Page 458**, (16.12): "k^{2}" on the l.h.s. should simply be
"k". (Thanks to Ranjan Laha.).

**Page 459**, end of paragraph containing (16.16): current
observations indicate that about 30% of the critical density is in
matter, and about 70% in "Dark Energy" with negative pressure, the
simplest example of which is a cosmological constant.

**Page 460**, (16.19): a power -1 is missing on the rhs, i.e. it
should be (1+z)/ R(t_{0}). (High redshifts z correspond to an
earlier, hotter, Universe.) (1^{st} print only.)

**Page 486**, just after the third bullet: "done" should read
"one". (1^{st} and 2^{nd} print only.)

__Chapter 17__

**Page 502**, Table, mGMSB entry for SU(2) doublet sleptons: The
coefficient G' should appear linearly, as for the other sfermions, not
as square. (1^{st} print only.)

__Appendix A__

**Page 507**: Note that the second diagram treats a negative
chargino as incoming particle, as indicated by the arrows. The
Feynman rule for outgoing positive chargino can be obtained by simply
taking the conjugate of the first vertex rule. (Thanks to Sascha
Bornhauser.)

**Page 512**: In Fig. 9.9 both sfermions have to be identical,
i.e. \tilde{f} = \tilde{f}'.

**Page 517**, Fig. 9.14: In the upper figure the label on the
outgoing solid (fermion) line should be f' rather than f. In the lower
figure the label on the outgoing dotted (sfermion) line should be
\tilde f' rather than f. (1^{st} and 2^{nd} print only.)

**Page 518**, Fig. 9.15: In the upper figure the label on the
outgoing solid (fermion) line should be f' rather than f. In the lower
figure the label on the outgoing dotted (sfermion) line should be
\tilde f' rather than f. (1^{st} and 2^{nd} print only.)

**Page 519**, Fig. 9.16: In the upper figure the label on the
outgoing solid (quark) line should be q_{i } rather than
q_{s}. In the lower figure the solid (quark) line should be
incoming, rather than outgoing, and should have label q_{i }
rather than q_{s}; moreover, the dotted (squark) line should
be outgoing rather than incoming. (1^{st} and 2^{nd} print

__Appendix B__

**Page 522**: As stated in the first paragraph of Sec. 10.4, the couplings
of the charged Higgs bosons are written for a single generation of quarks. The
extension to more than one generation proceeds as follows: In the second
Feynman diagram in Fig. 8.1., when f_{u} stands for quark u_{i}
and f_{d} stands for d_{j}, the vertex should be multiplied
with V^{qL}_{ij}, where V^{qL} is the CKM matrix
introduced on p.175. Similarly, in the third Feynman diagram in Fig. 8.1,
when f_{u} stands for quark u_{i} and f_{d} stands for
d_{j}, the vertex should be multiplied with
(V^{qL+})_{ji}, where V^{qL+} is the hermitian
conjugate of the CKM matrix V^{qL}. (Thanks to Andreas Crivellin.)
