Differential cross sections of the Higgs boson measured in the diphoton decay channel using 8 TeV pp collisions

This note presents differential cross section measurements of the Higgs boson, produced in $sqrt{s}=8$ TeV proton-proton collisions and decaying to a pair of photons. The dataset used corresponds to an integrated luminosity of $20.3 ext{ fb}^{−1}$ collected by the ATLAS detector at the LHC in 2012. With its high signal selection efficiency, the diphoton decay channel is ideally suited to probe the underlying kinematic properties of the signal production and decay. Measurements for several diphoton and jet distributions are made for isolated photons within the geometric acceptance of the detector and are corrected for experimental acceptance and resolution. Results are compared to several theoretical predictions at the particle-level.
