Search for supersymmetry in pp collisions at s=1.96TeV using the trilepton signature for chargino-neutralino production

We use the three lepton and missing energy trilepton signature to search for chargino-neutralino production with 2.0fb-1 of integrated luminosity collected by the CDF II experiment at the Tevatron pp collider. We expect an excess of approximately 11 supersymmetric events for a choice of parameters o...

description We use the three lepton and missing energy trilepton signature to search for chargino-neutralino production with 2.0fb-1 of integrated luminosity collected by the CDF II experiment at the Tevatron pp collider. We expect an excess of approximately 11 supersymmetric events for a 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 145GeV/c2 for a specific choice of parameters. © 2008 The American Physical Society.
