Precise Predictions for Standard Candles and New Physics at the LHC and Future Colliders, Dr. Christian Schwinn (Univ. Freiburg)

While the Standard Model of particle physics provides a good description of data from
collider and low-energy experiments (including the recent discovery of a Higgs-boson
candidate), it cannot be a complete description of nature as indicated e.g. by the evi-
dence for dark matter. Physics beyond the Standard Model might manifest itself directly,
e.g. in the form of new particles discovered at the LHC, or indirectly through quantum
corrections on precision observables. Precise theoretical predictions are required in both
scenarios: for "standard candle" processes that allow to measure input parameters of
the standard model (e.g. the top-quark and W-boson masses) and for production proc-
esses of new particles in order to distinguish different possible extensions of the stan-
dard model.
In this talk I will describe methods and examples for precise calculations, both for direct
production processes of new particles (exemplified by supersymmetric partners of
quarks and gluons) and for processes relevant for the top-quark and W-boson mass
measurements at the Tevatron, the LHC and a planned future electron-positron collider.
