Abstract: (PoS)
One of the fundamental properties of the Higgs boson, its mass, is measured by studying the invariant mass of the and diphoton decay channels with about 36 fb of data collected by the ATLAS experiment at the Large Hadron Collider (LHC). Since in these channels the final state can be fully reconstructed, an invariant mass peak with a good experimental resolution can be obtained in a model independent way and used as an input to compare other Higgs properties measurements with the SM predictions. The measured values of the Higgs boson mass for the and decay modes are GeV and GeV respectively, and the mass derived from the combined fit is GeV. These results are in good agreement with the LHC Run-1 average of GeV.- talk: Venice 2017/07/05
