Signal-background interference effects in Higgs-mediated diphoton production beyond NLO

In this talk I will consider signal-background interference effects in  Higgs-mediated diphoton production at the LHC. The inclusion of such effects results in a shift of the diphoton invariant mass distribution and in a destructive contribution to the total cross section.  As pointed out in earlier works, one can exploit interference studies to put bounds on the Higgs boson decay width. After reviewing the Higgs interferometry framework I will present an extension  of this analysis up to NNLO QCD in the soft-virtual approximation.
