Abstract: A search for τ slepton pair production in proton-proton collisions at a center-of-mass energy of 13 TeV is presented. The data correspond to an integrated luminosity of 77.2 fb−1 collected with the CMS detector in 2016 and 2017. The search is carried out in events with a pair of τ leptons in the final state, expected from each τ slepton decaying into a τ lepton and a neutralino. We consider events in which both τ leptons decay hadronically, as well as events in which one of the τ leptons decays hadronically while the other decays to an electron or a muon. The observed data are consistent with the standard model background expectation, and the results are interpreted as upper limits on the cross section for τ slepton pair production in different scenarios. In the scenario of a purely left-handed τ slepton decaying to a nearly massless neutralino, the strongest limits are obtained for a τ slepton mass of 125 GeV, corresponding to 1.14 times the theoretical cross section. | ||
