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 model, only light flavor squarks are accessible and 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/wino triplet, 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. It would be interesting to see the limits of the all-hadronic analyses to this challenging topology.
