Search for new physics using events with two same-sign isolated leptons in the final state at CMS

Abstract

We present a search for new physics using events with two same-sign isolated leptons with the presence of b-jets in the final state, targetting SUSY scenarios by strong production of squarks and gluinos where the 3rd generation squarks are lighter than other squarks. No excess above the standard model background is observed. The results are interpreted in various SUSY models, and we are able to exclude gluino (sbottom) masses up to 1000 (450) GeV at 95% CL.
