====== Research Group of Prof. Dr. Dieter Zeppenfeld ======
===== General field of research =====
Calculation of cross sections and study of processes that can be studied at the most energetic accelerators, in particular LHC, FCC or future e<sup>+</sup>e<sup>-</sup> accelerators.

===== Motivation =====
  * Higgs search und origin of mass
  * Search for supersymmetry (SUSY partners)
  * Extra dimensions and other exotica

===== Methods =====
  * Theory of electroweak processes
  * QCD effects (Jets, radiative corrections, ...)
  * Numerical simulation via Monte Carlo

===== Example: Higgs produktion in WW fusion =====

===== Challenge =====
Complex signal with very good possibilities for background reduction and exact signal measurement ⇒ better simulations of signal and background are needed.. 

===== Examples for Bachelor thesis topics =====
{{anchor:thesis}}
  * Improved phase space generation for vector boson fusion processes
  * Effective field theory predictions for helicity amplitudes in vector boson fusion

===== Examples for Master thesis topics =====
  * Central jet veto in vector boson scattering in NLO QCD
  * QCD corrections to Wjjj production via vector boson fusion
