The search is carried out in events containing two $${\uptau }_{}^{}$$ τ leptons in the final state, on the assumption that each $${\uptau }_{}^{}$$ τ slepton decays primarily to a $${\uptau }_{}^{}$$ τ lepton and a neutralino. Events are considered in which each $${\uptau }_{}^{}$$ τ lepton decays to one or more hadrons and a neutrino, or in which one of the $${\uptau }_{}^{}$$ τ leptons decays instead to an electron or a muon and two neutrinos. The data, collected with the CMS detector in 2016 and 2017, correspond to an integrated luminosity of 77.2$$\,\text {fb}^{-1}$$ fb-1 . The observed data are consistent with the standard model background expectation. The results are used to set 95% confidence level upper limits on the cross section for $${\uptau }_{}^{}$$ τ slepton pair production in various models for $${\uptau }_{}^{}$$ τ slepton masses between 90 and 200$$\,\text {GeV}$$ GeV and neutralino masses of 1, 10, and 20$$\,\text {GeV}$$ GeV . In the case of purely left-handed $${\uptau }_{}^{}$$ τ slepton production and decay to a $${\uptau }_{}^{}$$ τ lepton and a neutralino with a mass of 1$$\,\text {GeV}$$ GeV , the strongest limit is obtained for a $${\uptau }_{}^{}$$ τ slepton mass of 125$$\,\text {GeV}$$ GeV at a factor of 1.14 larger than the theoretical cross section. en dc.language.iso en dc.rights openAccess dc.source European Physical Journal C dc.title Search for direct pair production of supersymmetric partners to the τ lepton in proton–proton collisions at √s=13TeV en dc.type article en dc.rights.license BY dcterms.abstract Ћирковић, Предраг; Тумасyан, A.; Aдам, W.; Aмброги, Ф.; Бергауер, Т.; Aджић, Петар; Деветак, Дамир; Ђорђевић, Милош; Миленовић, Предраг; Милошевић, Јован; Сирунyан, A.; Стојановић, Милан; dc.rights.holder © 2020, CERN for the benefit of the CMS collaboration dc.citation.volume 80 dc.citation.issue 3 dc.citation.spage 189 dc.identifier.wos 000528546600002 dc.identifier.doi 10.1140/epjc/s10052-020-7739-7 dc.description.other CMS Collaboration (ukupan broj autora: 2338) dc.type.version publishedVersion dc.identifier.scopus 2-s2.0-85080991473 dc.identifier.fulltext http://vinar.vin.bg.ac.rs/bitstream/id/22169/Sirunyan2020_Article_SearchForDirectPairProductionO.pdf
