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

Tijdschriftbijdrage - Tijdschriftartikel

A measurement of the mass of the Higgs boson in the diphoton decay channel is presented. This analysis is based on 35.9fb −1 of proton-proton collision data collected during the 2016 LHC running period, with the CMS detector at a centre-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 H=125.78±0.26GeV. This is combined with a measurement of m H already performed in the H→ZZ→4ℓ decay channel using the same data set, giving m H=125.46±0.16GeV. This result, when further combined with an earlier measurement of m H using data collected in 2011 and 2012 with the CMS detector, gives a value for the Higgs boson mass of m H=125.38±0.14GeV. This is currently the most precise measurement of the mass of the Higgs boson.
