Search for direct τ slepton pair production in proton-proton collisions at s= 13 TeV
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 fb1 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.
