Dear All,
 
We have the pleasure of inviting you to the Particle Theory Seminar on Friday, April 5 at 13:00, which will be given by

Stefan Hoche (Fermilab)

entitled

„Precision simulations of light and heavy jets".

Abstract:

I will introduce a new parton shower algorithm for the numerical resummation of large logarithms in perturbative QCD. It is based on a novel matching of the classical radiation pattern to the collinear limit, combined with a recoil scheme that satisfies the criteria for next-to-leading logarithmic precision. I will also present an extension of the method to heavy quark evolution and introduce a Monte-Carlo method to implement heavy quark production in a variable flavor number scheme. First applications of the parton shower to the Drell-Yan transverse momentum spectrum, and of the variable flavor number scheme to the fully differential simulation of ttbb will be discussed.

The speaker will be on-site, local participants are invited to meet in the seminar room D-2-02.
