 +===== Information on Bachelor and Master Theses =====
 + {{anchor:thesis}}
 +If you are interested in a Bachelor,  Master or PhD thesis in the field of
 +precision calculations and particle phenomenology, please contact Gudrun Heinrich [[gudrun.heinrich@kit.edu|via email]].
 +The thesis may involve work with programs based mainly on python and
 +C++ (for example the program  [[https://github.com/gudrunhe/secdec/releases|pySecDec]]) or python and fortran90 (for example the program  [[https://github.com/gudrunhe/gosam|GoSam]]).
 +However, subjects where the focus is more on analytic calculations are also possible.
 +The students will be part of an active and lively research group,
 +comprising also international collaborators.
 +
 +===== Examples for Bachelor thesis topics =====
 +   * Untersuchung der Effekte anomaler Kopplungen im Higgs- und top-quark-Sektor am LHC
 +   * Numerische Untersuchung von Loop-Integralen basierend auf dem Programm [[https://github.com/gudrunhe/secdec/releases|pySecDec]]
 +   * Untersuchung extremer kinematischer Bereiche (Hochenergie-Limes, kleine Massen, etc.)
 +   * Untersuchung von Prozessen an zukünftigen Lepton-Beschleunigern
 +  
 +
 +===== Examples for Master thesis topics =====
 +  * Investigation of effects from so far unknown particles/interactions in Higgs boson pair production
 +  * Higgs+Jet production as a window to New Physics
 +  * Study of multi-loop-integrals with heavy quarks and Higgs bosons based on the program [[https://github.com/gudrunhe/secdec/releases|pySecDec]]
 +  * Anomalous couplings at high and low energies
 +  * Application of machine learning methods to loop amplitudes
