Evidence for Higgs boson decay to a pair of muons

by Andrea Marini (CERN)


ZOOM (pass 092020)
The seminar presents the search and the first evidence for the Higgs boson decay to a pair of muons performed by the CMS Collaboration.  The analysis is based on the full datasets collected at 13 TeV during Run 2 of the LHC, corresponding to 137 fb-1. 
The characteristics of the four main Higgs boson production modes, gluon fusion, vector-boson fusion, and associated production with a W or Z vector boson or with a top-quark pair, are exploited to increase the sensitivity of the search. 
An excess over the expected SM background is observed in data with a significance of 3.0 standard deviations,  consistent with the presence of the Higgs boson decay to muons.
