Effective Theory Predictions for LHC Processes

Monday, 25th October, 12:00hs - IFAE Seminar room.

Speaker: Christian Bauer  (LBNL, Berkely)

Abstract:

This talk will give an introduction to effective field theories and how they can improve our theoretical understanding of collider physics. After discussing the basic ideas of effective theories, I will present briefly a relatively new effective theory called SCET which is suitable for collider physics. I will then

introduce and discuss three different applications of this effective theory to LHC physics: 1) Proving the factorization of SM processes into perturbative partonic cross sections and non-perturbative universal parameters such as parton distribution functions, 2) Resumming large logarithmic terms threatening the convergence of perturbation theory and 3) Constructing a new event generator called Geneva that merges NLO calculations with parton shower algorithms.
