Request Description and Potential
Reason for request:
Limits on light flavor squarks are now approaching 1 TeV. However, the limits should be greatly reduced if the spectrum is altered by including an intermediate particle in the decay chain. In this simplified models, the gluinos are decoupled, and thus the main production mode is squark-antisquark pair-production. The squarks now decay to an intermediate particle, to a chargino or a wino, plus a jet. The chargino/wino then decays to a vector boson and a neutral state. This scenario can occur in the MSSM where the right handed squarks are decoupled from the left-handed ones, and in the NMSSM where the LSP is a singlino. The all-hadronic channels now become a sub-optimal place to look for this topology given the sizable decay rates into leptons and the reduced visible and missing energy in the event. However, channels with leptons should be sensitive to this signature. In particular, the signal should give events with three or more leptons and missing energy.
