A measurement of the Higgs boson mass in the diphoton decay channel

Understand

A measurement of the mass of the Higgs boson in the diphoton decay channel is presented.

• This analysis is based on 35.9 fb$^{-1}$ of proton-proton collision data collected during the 2016 LHC running period, with the CMS detector at a center-of-mass energy of 13 TeV.
• A refined detector calibration and new analysis techniques have been used to improve the precision of this measurement.
• The Higgs boson mass is measured to be $m_\mathrm{H} =$ 125.78 $\pm$ 0.26 GeV.
