RTG Seminar by Thomas Becher

Abstract:

In the past hadron colliders were considered discovery machines at which one is able to search for striking signals such as new resonance peaks, but which are not suited for detailed studies and precision measurements. The LHC is strongly challenging this view as we are now using this collider for precision physics. I will review some of the recent progress — as well as the challenges — in the precise theoretical prediction of collider processes. Important tools are automated computations, resummations of perturbation theory, and Soft-Collinear Effective Theory (SCET).
