### Lecture winter term 2008/2009:

## Advanced topics in particle physics

#### by Rainer Stamen and Markos Maniatis

Lecture: Tuesday, 9:15 - 11am

Journal Club: Thursday, 1:15 - 3pm biweekly.

Place: Lecture at KIP, HS 2, Jounal Club at KIP in 2.403

#### Current information

##### Note: Thursday, Jan 22 in the journal club, we would like
to discusse a
paper about supersymmetry phenomenology.

This is a rather lengthy paper and we suggest to focus
on sections 1 to 4.

Not every detail has to be discussed.

If there are any questions please do not
hesitate to ask us!

Further literature - but which is probably not necessary to read:

S. P. Martin: A Supersymmetry primer
##### Note: Thursday, Dec 11 in the journal club, we had a discussion of the
paper about supersymmetry in quantum mechanics.

This is a rather lengthy paper and we suggest to focus
on the section 2 as well as 2.1 including equation (59).

As is shown in detail supersymmetry in quantum mechanics relates two different
potentials in the Schrödinger equation.

Further literature - which is probably not necessary to read
- to this subject:

G. Junker, SUSY Methods in Quantum and Statistical Physics (1996)

##### Note: Thursday, Nov 27 in the journal club, we
discussed the paper from the D0 collaboration at Fermilab
about the associated W and Higgs boson production.

##### Note: Thursday, Nov 13 in the journal club, we discussed the
paper from Peter W. Higgs about the
so-called Higgs mechanism.

This is a rather short paper and maybe we could extend the discussion
to a slightly more general overview.

Textbooks to this topic:

Peskin/Schöder : An Introduction to Quantum Field Theory

Nachtmann: Elementary Particle Physics: Concepts And Phenomena

Böhm/Denner/Joos : Gauge Theories of the Strong and Electroweak Interactions

Ryder : Quantum Field Theory

##### Note: Thursday, Oct 23 in the journal club, we discussed the
paper
about the measurement of structure functions at the Desy/H1 experiment in Hamburg.

##### Note: Thursday, Oct 16 in the journal club, we discussed the
paper about Yang-Mills theory.

We focus on the part from the biginning of the paper up to eq. (12).

##### Note: Thursday, Oct 9 in the journal club, Rainer Stamen has presented an
overwiev to scientific information.

#### Lecture

Various modern subjects of particle physics shall be discussed in
the lecture part on Tuesday (see table below).
In the journal club on Thursday some aspects of these subjects
should be worked out in more detail.
Here we ask the students to introduce together with us papers which are closely
related to the lecture.

In the lecture part we start with an introduction of
the Standard Model, that is
QCD as well as the electroweak interactions.
Some challenges on the experimental side like the search for
the Higgs boson as well as on the theoretical side, like
the quadratical divergences to the Higgs boson mass will
be discussed.
Eventually, some promising experiments and models
focussing on physics beyond the Standard Model are presented.

The students are assumed to have listen to the lecture
"Introduction to elementary particle physics" and should
have some knowledge of quantum field theory.
