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

TL;DR

This paper reports a search for new physics phenomena in events with two same-sign isolated leptons at CMS, focusing on specific SUSY scenarios, but finds no significant deviations from the standard model predictions.

Contribution

It introduces a search strategy targeting two different SUSY scenarios using same-sign leptons, with interpretation in various SUSY models.

Findings

No excess above standard model background observed

Results constrain SUSY parameter space

Analysis demonstrates sensitivity to specific SUSY signatures

Abstract

We present a search for new physics using events with two same-sign isolated leptons with/out the presence of b-jets in the final state, targetting two very different SUSY scenarios, one dominated by strong production of squarks and gluinos where the 3rd generation squarks are lighter than other squarks and the other dominated by electroweak production neglecting completely any strongly interacting particles. No excees above the standard model background is observed. The results are interpreted in various SUSY models.
