- Time and Place:
Tuesday, 08:15 to 10:00, lecture hall, HISKP;
Thursday, 9:15 to 10:00, lecture hall, HISKP (on the ground floor).

- Tutorials:
Time and Place: Tuesday, 3:15 to 5:00 p.m.,
AVZ, rm. 0.021 (Uuml;bungsroom 5); and Wednesday, 2:15 to 4:00 p.m.,
HISKP, seminar room 2.
Tutors: Wenbin Zhao (Wegelerstr.10, room 2.021; tel. 3718, e-mail

At least at the beginning of the semester the lecture will be given in
hybride mode again: I'll give the lecture in the lecture hall, but it will
also be live-streamed via Zoom, and a recording of the lecture will be made
available on eCampus for one week; the recording will be deleted after one
week, partially for reasons of data privacy issues. The Zoom link
for this lecture is
here . The "coordinates" are:

At least for the time being it is strongly recommended that you
wear a mask at least while moving inside university buildings; of course,
you are free to also wear a mask during the lecture itself. (I will not wear
one during the lecture, in order to be more easily understood.) As far as I
know there will be no more access restrictions during the summer term (no more
"3G rule").
The assignment sheets can be downloaded
here.
The figures shown on the projector during class can be
found here.
Only students who have done at least 50% of the homework of this
class will be permitted to take the final exam! In order to
check this, the tutor will pass a list at the beginning of each
tutorial, in which the students will indicate which problem(s) they
solved. The tutor will use this list to call someone to the board,
to present the solution. The solution need not be entirely correct
to be counted towards the 50%, but you must have made a serious
attempt at solving the problem.
If desired, students can also
hand their written solutions to the tutor, asking for it to be
corrected. This may be of interest to you if your solution differs
from the one being presented, and you wish to know whether your
solution is also ok.
This lecture deals with particle physics aspects relevant for our (tentative)
understanding of the Universe, in particular of the very early universe,
i.e. the era up to and including Big Bang nucleonsynthesis.
The lecture is aimed at students interested in experimental and/or theoretical
(astro-)particle physics. Prior knowledge of relativistic quantum mechanics,
and the Standard Model of particle physics will be assumed. I will occasionally
use results from Quantum Field Theory, but one should be able to follow this
class without having taken lectures in Quantum Field Theory first. (Of course,
everybody interested in particle theory should take the QFT classes, too!)
Similarly, I will use some results from General Relativity (chiefly, the
Friedman Robertson Walker metric) without derivation. Prior knowledge of
popular extensions of the Standard Model - in particular, Supersymmetry - is
helpful but not essential.
The following topics will be covered:
1) Introduction: the evolution of the universe in 30 minutes
2) Friedman-Robertson-Walker metric
3) Thermodynamics in an expanding universe
4) Big Bang Nucleosynthesis as a laboratory for New Physics
5) How Dark Matter may have been made
6) Baryogenesis: making baryons
7) Inflation: basics and simple models
8) Inflation: quantum fluctuations as seed for structure formation
9) Inflation: reheating the Universe
Particle physics aspects of today's universe will not be
covered. Many of these topics will be covered in a dedicated lecture next
semester (i.e. in the WS 2022/23).
Literature:
M.E. Turner and E.W. Kolb, The Early Universe, is still the standard
text, written from a particle physics oriented perspective.
Drees, Godbole and Roy, Theory and Phenomenology of Sparticles, gives an
in-depth treatment of supersymmetry, with emphasis on phenomenological
aspects, and a lengthy chapter on cosmological aspects.
Seminar on Advanced Quantum Field Theory (with
Prof. Claude Duhr and Dr. Florian Loebbert)
- Time and Place :
Wednesday, 10:15 to 12:00, PI, BCTP Seminar Room.
- First Meeting: April 13, 2022 (in the second (!) week
of classes).
- Last possible seminar: July 13, 2022.
This seminar will cover some topics in modern quantum field theory
that are typically not covered in the two regular QFT lectures covered
here. We will cover both topics that are immediately relevant for
phenomenology and some more formal topics.
As usual in a student seminar, students will give hour-long talks on
a topic of their choice. The Literature relevant for each topic will be
provided by the supervisor.
The students should give a practice talk to the advisor about one week
before the real talk; the latter will be graded (for MSc students). This
"practice talk" should at least include going through the material / slides
together with the advisor.
Possible topics include:
R/xi gauge in theories with broken symmetry (as in the elw sector of the SM)
Radiative symmetry breaking
Running parameters and the renormalization goup
The electroweak equivalence theorem
The renormalization of the electroweak sector of the SM
Electroweak precision tests
See-saw mechanism and neutrino masses
The planar limit of Yang-Mills theory ("Large N_{C}")
Compactification of additional spatial dimensions (Kaluza-Klein theories)
N=4 Super Yang-Mills theory
The Coleman-Mandula theorem
The Haag-Lopuszanski-Sohnius theorem
Master and Doctoral Theses
Please contact me directly regarding possible topics.
I expect a Master thesis to contain new, previously unknown, scientific
results. So far nearly all Bonn Diploma and Master theses in my group have led
to journal publications. While I am (nearly) always available for questions and
discussions, I generally encourage students to work as independently as
possible. This means that I do not require regular progress reports; I
expect students who have some questions to come to me on their own
initiative.
Also, students who have their own idea about a topic for a Master thesis
are very welcome, if it falls in my area of expertise.
If you are interested, please contact me directly for further information. I
also encourage you to talk to some of the other members
of my group before committing yourself.
