| Summary: | A search for the electroweak production of supersymmetric particles in protonproton collisions at a center-of-mass energy of 13 TeV is presented in final states with a
τ lepton pair. Both hadronic and leptonic decay modes are considered for the τ leptons.
Scenarios involving the direct pair production of τ sleptons, or their indirect production
via the decays of charginos and neutralinos, are investigated. The data correspond to an
integrated luminosity of 35.9 fb−1
collected with the CMS detector in 2016. The observed
number of events is consistent with the standard model background expectation. The
results are interpreted as upper limits on the cross section for τ slepton pair production in
different scenarios. The strongest limits are observed in the scenario of a purely left-handed
low mass τ slepton decaying to a nearly massless neutralino. Exclusion limits are also set
in the context of simplified models of chargino-neutralino and chargino pair production
with decays to τ leptons, and range up to 710 and 630 GeV, respectively |
