Sensitivity to Sparticle Masses and Model Parameters in Direct Chargino-Neutralino Production

The possibility to determine sparticle masses in the 3 lepton + no jets + ET missing final states from chargino1-neutralino2 pair production is studied. It is based on the kinematics of neutralino2 -> neutralino1 l+l- and neutralino2 -> lepton slepton -> neutralino1 l+l- leptoni...

description The possibility to determine sparticle masses in the 3 lepton + no jets + ET missing final states from chargino1-neutralino2 pair production is studied. It is based on the kinematics of neutralino2 -> neutralino1 l+l- and neutralino2 -> lepton slepton -> neutralino1 l+l- leptonic decays. The analysis is carried out within the framework of the minimal SUGRA model, where the mass measurement of the lightest neutralino ( neutralino1) allows to constrain the common gaugino mass ( m_1/2). The sensitivity to the common scalar mass ( m0) is also observed from the 3 lepton + no jets + ET missing events rate. The region of ( m0, m1/2) plane, where these methods are applicable, is determined.
