Dilepton transverse momentum distribution variables at the Tevatron and the LHC

  • Event time: 1:00pm
  • Event date: 7th March 2012
  • Speaker: Professor Simone Marzani (University at Buffalo)
  • Location: Lecture Theatre B,

Event details

The D0 collaboration has introduced new variables to accurately probe the low transverse momentum region of Z boson production at hadron colliders.I present a state-of-the-art analytical calculation of these new variables that contains the resummation of large logarithms up to next-to next-to leading logarithmic accuracy, matched to a full next-to leading order calculation. The theoretical result is performed accounting for the experimental cuts introduced by the D0 collaboration, so it can be immediately compared to data. The comparison to the experimental data gives important information on the size of non-perturbative effects. I also present predictions for the LHC.

The Particle Physics Theory seminar is a weekly series of talks reflecting the diverse interests of the group. Topics include analytic and numerical calculations based on the Standard Model of elementary particle physics, theories exploring new physics, as well as more formal developments in gauge theories and gravity..
