Interference effects in the H → γγ + 2 jets channel at LHC
We compute the interference between the resonant process pp → H(→ γγ) + 2 jets and the corresponding continuum background at leading order. For the Higgs signal, we include gluon fusion and vector boson fusion production channels, while for the background we consider all tree-level contributions, in...
