Search for Supersymmetry Using the Trilepton Signature of Chargino-Neutralino Production

Creators

Description

We use the three lepton and missing energy 'trilepton' signature to search for chargino-neutralino production with 2.0 fb-1 of integrated luminosity collected by the CDF II experiment at the Tevatron p(bar p) collider. We expect approximately 11 supersymmetric events for a specific choice of parameters of the mSUGRA model, but our observation of 7 events is consistent with the standard model expectation of 6.4 events. We constrain the mSUGRA model of supersymmetry and rule out chargino masses up to 145 GeV/c2 for a specific choice of parameters
