Search for SUSY with multileptons in 13 TeV data

A search for new physics is performed using events with multileptons ($\ge3$ electrons or muons) in the final state using the CMS detector. Results are based on a sample of proton-proton collisions at a centre-of-mass energy of 13 TeV at the LHC corresponding to an integrated luminosity of 2.3 fb$^{-1}$. Search regions have been defined by the number of b-tagged jets, missing transverse energy, hadronic transverse energy, and the invariant mass of opposite-sign, same-flavor dilepton pairs in the events. No excess above the standard model background expectation is observed. In a model with gluino pair production where the gluino decays to two top quarks and a neutralino, gluinos with mass less than 1125 GeV are excluded.
