In this paper we consider signal-background interference effects in Higgs-mediated diphoton production at the LHC. After reviewing earlier works that show how to use these constrain Higgs boson total decay width, provide predictions beyond NLO accuracy for and related observables, study impact of QCD radiative corrections on width determination. particular, so-called soft-virtual approximation ...
