Dear all,
Tomorrow we have a theory seminar at 2pm *in room N328*. The speaker is Chris Wever from Utrecht, who will talk about Soft and Coulomb resummation. See below for details.
Regards, Pierre
Speaker: Chris Wever
Date/place: May 23, 2pm, N328 Speaker: Chris Wever (Utrecht) Title: Soft and Coulomb resummation: squark and gluino production at the LHC
abstract
We consider the production of strongly interacting, heavy SUSY pairs at the LHC. When the centre of mass energy is close to the production threshold of the pair, the corresponding cross sections receive large higher-loop QCD corrections. These corrections are classified as the so-called soft logarithms and Coulomb singularities and they lead to a break down of the usual perturbative expansion. In this talk I review the origin of these large corrections and explain how they can be resummed by using Effective Field theories. Finally, I will present some resummed results for the pair production cross sections of heavy squarks and gluinos. Based on: arXiv:1202.2260 and 1211.3408.
