Higgs mass measurement at ATLAS

This talk describes the Higgs mass measurement in ATLAS using 25 fb-1 of 7 and 8 TeV pp data produced by the LHC. The measurement was performed in the H->yy and H->ZZ->4l channels. Improvements were achieved in the electron/photon/muon calibration as well as in the analysis methods, reducin...

Sumario:This talk describes the Higgs mass measurement in ATLAS using 25 fb-1 of 7 and 8 TeV pp data produced by the LHC. The measurement was performed in the H->yy and H->ZZ->4l channels. Improvements were achieved in the electron/photon/muon calibration as well as in the analysis methods, reducing the systematic uncertainties by a factor of 2 with respect to the 2013 publication
