A flavour-independent Higgs boson search in e+e− collisions at√s up to 209 GeV
Di-photon cross section measurement and Higgs sensitivity study in the two-photon final state with the ATLAS detector
This work is done with the ATLAS collaboration. Three independent methods are proposed to measure the photon trigger efficiency. They are first evaluated using Monte Carlo simulation and then applied

TLDR
Three independent methods are proposed to measure the photon trigger efficiency and a deterioration of 4% in the exclusion limit is observed after incorporating the systematic uncertainty arising from the resolution of the di-photon invariant mass.
