Resumen:
We present the full O(αS2) computation of the in- terference effects between the Higgs diphoton signal and the continuum background at the LHC. While the main contri- bution to the interference originates on the gg partonic sub- process, we find that the corrections from the qg and qq ̄ channels amount up to 35 % of it. We discuss the effect of these new subprocesses in the shift of the diphoton invariant mass peak recently reported by S. Martin in (Phys. Rev. D 86:073016, 2012)
