This result combines searches in four exclusive categories targeting the production of the Higgs boson via gluon fusion, via vector boson fusion, in association with a vector boson, and in association with a top quark-antiquark pair. The analysis is performed using proton-proton collision data at s $$\sqrt{s}$$ = 13 TeV, corresponding to an integrated luminosity of 137 fb −1, recorded by the CMS experiment at the CERN LHC. An excess of events over the back- ground expectation is observed in data with a significance of 3.0 standard deviations, where the expectation for the standard model (SM) Higgs boson with mass of 125.38 GeV is 2.5. The combination of this result with that from data recorded at s $$\sqrt{s}$$ = 7 and 8 TeV, corresponding to integrated luminosities of 5.1 and 19.7 fb −1, respectively, increases both the expected and observed significances by 1%. The measured signal strength, relative to the SM prediction, is 1.19 − 0.39 + 0.40 stat − 0.14 + 0.15 syst $${1.19}_{-0.39}^{+0.40}{\left(\mathrm{stat}\right)}_{-0.14}^{+0.15}\left(\mathrm{syst}\right)$$ . This result constitutes the first evidence for the decay of the Higgs boson to second generation fermions and is the most precise measurement of the Higgs boson coupling to muons reported to date. en dc.language.iso en dc.rights openAccess dc.rights.uri https://creativecommons.org/licenses/by/4.0/ dc.source Journal of High Energy Physics dc.title Evidence for Higgs boson decay to a pair of muons en dc.type article en dc.rights.license BY dcterms.abstract Милошевић, Јован; Сирунyан, A.; Тумасyан, A.; Aдам, W.; Бергауер, Т.; Драгицевиц, М.; Aджић, Петар; Ћирковић, Предраг; Ђорђевић, Милош; Миленовић, Предраг; dc.rights.holder © 2021 The Author(s) dc.citation.volume 2021 dc.citation.issue 1 dc.citation.spage 148 dc.identifier.wos 000613472700001 dc.identifier.doi 10.1007/JHEP01(2021)148 dc.description.other CMS Collaboration (ukupan broj autora: 2357) dc.type.version publishedVersion dc.identifier.scopus 2-s2.0-85107384471 dc.identifier.fulltext https://vinar.vin.bg.ac.rs/bitstream/id/24397/Sirunyan2021_Article_EvidenceForHiggsBosonDecayToAP.pdf
