Higgs boson property measurement in the H → γγ decay channel at 13TeV with ATLAS experiment

Following the upgrade of the LHC to allow proton-proton collisions at √ S =13TeV, it is important to continue Higgs property measure- ment through the γγ golden decay channel. Fur- ther more, the increased center-of-mass energy results in much larger cross sections for events at high partonic certer-of-mass energy, which im- plies improved sensitivity to a variety of inter- esting physics processes, such as Higgs bosons produced at high transverse momentum or Higgs produced in association with a top-antitop pair.
