    1. 12. 2006 - 30. 11. 2010
Bearbeitete Themenfelder:
Aktuelle Themenfelder:
  • Radiative Corrections:
    If low energy Supersymmetry is realized in nature, LHC will produce supersymmetric particles copiously and the ILC will be an ideal environment for performing precision measurements. Experimental accuracies are expected from the per-cent down to the per-mille level. These must be matched from the theoretical side. Therefore, the inclusion of radiative corrections is mandatory.
  • Charge-Parity Violation (CPV):
    SUSY contains possible new sources of CPV through additional CPV phases which lead to new effects at colliders. The phenomena of CPV are important also because this is likely to be the key to understanding the observed abundance of matter over antimatter.
  • Flavour Violation (FV):
    In the Standard Model FV is only possible due to the CKM matrix. New sources of FV can appear within SUSY models in the quark and also in the leptonic sector. Despite some strong constraints from B-physics the effects can be large.
  • General phenomenological SUSY studies:
    Covers studies not belonging to the above three subprojects, e.g. Monte Carlo studies of squark production at the ILC and gravitino three-body decays.
Perspektiven (nächste 5 Jahre):
  • Radiative Corrections
  • Gravitino physics
  • Quark Flavour Violation
  • CP Violation
  • Global Fits
