Searches for electroweak production of charginos, neutralinos, and sleptons decaying to leptons and W, Z, and Higgs bosons in pp collisions at 8 TeV

TL;DR

This paper reports on searches for supersymmetric particles like charginos, neutralinos, and sleptons in proton-proton collisions at 8 TeV, finding no deviations from the standard model and setting mass limits up to 720 GeV for charginos and 260 GeV for sleptons.

Contribution

First comprehensive search for electroweak supersymmetric particles decaying to leptons and bosons at 8 TeV with CMS, setting new mass exclusion limits.

Findings

No excess observed over standard model predictions.

Charginos excluded up to 720 GeV.

Sleptons excluded up to 260 GeV.

Abstract

Searches for the direct electroweak production of supersymmetric charginos, neutralinos, and sleptons in a variety of signatures with leptons and W, Z, and Higgs bosons are presented. Results are based on a sample of proton-proton collision data collected at center-of-mass energy sqrt(s) = 8 TeV with the CMS detector in 2012, corresponding to an integrated luminosity of 19.5 inverse femtobarns. The observed event rates are in agreement with expectations from the standard model. These results probe charginos and neutralinos with masses up to 720 GeV, and sleptons up to 260 GeV, depending on the model details.
