Request Description and Potential
Reason for request:
Many models of natural SUSY predict light stop squarks. These are fairly unconstrained if they decay to a top and near-massless LSP. Theorists have made estimates of the sensitivity of current searches to these particles (see, e.g., 1110.6444), but it would be useful to better understand the search efficiencies to see if a target search for light stops is warranted.
Additional Information:
I can provide LHE events for a range of stop masses.


It would also be interesting to have this for various scenarios, e.g. stop -> b W gravitino, stop -> b W bino, etc. The kinematics and amount of missing E_T can be rather different in the different cases.
