Elisabetta Furlan (Zurich):

A precise effective Higgs-gluon interaction beyond the Standard Model

Abstract:

The search for the Higgs boson is a primary objective at Tevatron and LHC. The dominant production mechanism is gluon fusion, for which new physics effects can lead to significant deviation from the standard model predictions. We compute the contribution of heavy particles in arbitrary representations of the Lorentz and colour groups to the production cross-section. We will present the construction of an effective Lagrangian where heavy particles are integrated out and the computation of the corresponding Wilson coefficient at three-loops.
