Thesis offers

The group continuously offers topics for Diploma Thesis and PhD thesis on the ZEUS Experiment at HERA, DESY, on the CMS Experiment at the Large Hadron Collider (LHC) at CERN and on the developement of detectors, i.e. silicon detectors. Many of the topics are commonly supervised with scientists from DESY or CERN. Current topics include:

• QCD, the physics of strong interactions. The focus here is on the investigation of jet properties and rates at HERA with the aim to better determine the gluon density in the proton and the strong coupling constant alpha_s. This is going to be extended to jet measurements at the LHC. Related to this is the investigation of the underlying event at both HERA and the LHC.

• Physics beyond the Standard Model, i.e. Supersymmetry. At HERA, SUSY processes with lepton number violation are searched for. At LHC, the focus is on models with conserved R-parity and final states including Gravitinos. P. Schleper, G. Steinbrück

• Closely related to the work on current detectors are the development of new silicon materials able to stand the high particle fluxes at the LHC by material engineering (doping). G. Lindström E. Fretwurst

• Design and development of new silicon sensors, including measurements for example at the DESY testbeam, are done for upgrades of the CMS pixel detector as well as for prototypes of new monolithic pixel detectors for a future linear e+e- collider. R. Klanner G. Steinbrück
