A complete O(αS2) calculation of the signal-background interference for the Higgs diphoton decay channel
We present the full O(αS2) computation of the interference effects between the Higgs diphoton signal and the continuum background at the LHC. While the main contribution to the interference originates on the gg partonic subprocess, we find that the corrections from the qg and qq̄ channels amount up...
