| Description | Joint Theory Seminar Speaker: Jon Walsh (Berkeley) Title: Vetoes in LHC Cross Sections: QCD and Electroweak Effects Host: Ennio Salvioni Room: 432 Abstract: Cross sections at the LHC are often measured with cuts to select exclusive numbers of final state jets or leptons. For jets, these cuts often degrade the precision of fixed order perturbation theory, and I will use the case of Higgs production to show how resummation can be used to provide robust predictions and improve the measurement of Higgs couplings. On the leptonic side, at high energies and large momentum exchange electroweak effects can become substantial, and the interplay between experimental cuts, virtual effects, and real radiation is more subtle. I will use Drell-Yan as a backdrop to discuss these issues and show when they can become phenomenologically relevant. |
