Search for Supersymmetry in Trilepton Final States with the DO Detector

TL;DR

This paper reports a search for supersymmetric particles in trilepton final states using data from the DO detector at Tevatron, finding no evidence of new physics and setting limits on production rates.

Contribution

First search for supersymmetry in trilepton final states at Tevatron with the DO detector, establishing new limits on chargino and neutralino production.

Findings

No excess above standard model expectations was observed.

Limits on production cross section times branching fraction were set.

The analysis constrains supersymmetric models in the studied channel.

Abstract

Data taken by the DO experiment at the proton-antiproton collider at Tevatron has been analyzed to search for signatures consistent with decay of charginos and neutralinos. The search is performed in final states with three leptons and missing transverse energy. No excess above the standard model expectation is observed and limits on the production cross section times branching fraction are set.
