Search for electroweak production SUSY in same-sign dileptons and multilepton final states with CMS

TL;DR

This paper reports a search for electroweak supersymmetry particles using CMS data, finding no excess over the standard model and setting limits on chargino and neutralino masses.

Contribution

First search using CMS 2016 data for electroweak SUSY in same-sign and multilepton final states with tau leptons, setting new mass limits.

Findings

No significant excess observed over standard model predictions.

Excluded chargino and neutralino masses up to 1150 GeV.

Results constrain SUSY models with specific parameters.

Abstract

Searches for direct electroweak production of charginos and neutralinos in signatures with two light leptons of the same charge and with three or more leptons including up to two hadronically decaying {\tau} leptons are presented . The full 2016 dataset of pp collisions recorded by CMS at a center-of-mass energy of 13 TeV is used, corresponding to an integrated luminosity of 35.9 /fb. The observed event rates are in agreement with expectations from the standard model. These results probe charginos and neutralinos with masses up to values between 225 and 1150 GeV, depending on the model parameters assumed.
