Extracting Higgs Boson Couplings from LHC Data

Abstract

We show how LHC Higgs boson production and decay data can be used to extract the gauge and fermion couplings of the Higgs boson. Incomplete input data leads to parameter degeneracies, which can be lifted by imposing theoretical assumptions. We show how successive theoretical assumptions affect the parameter extraction, starting with a general multi-Higgs doublet model and finishing with specific supersymmetric scenarios.
