Search for new physics in events with same-sign dileptons
Abstract: A search for new physics is performed using events with a pair of isolatedsame-sign leptons and jets 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 8~TeV at the LHC corresponding to an integrated luminosity of 19.5~fb${}^{-1}$. In order to be sensitive to a wide variety of possible signals beyond the standard model, we consider multiple search regions defined by the missing transverse energy, the hadronic energy, the number of jets and b-quark jets, and the transverse momenta of the leptons in the events. No excess above the standard model background expectation is observed and constraints are set on a number of new physics models. Information on event selection efficiencies is also provided so that the results can be used to confront an even broader class of new physics models.
