Study of RPV stop signals in paired dijet signatures

description In supersymmetry models squark is the superpartner of the top quark and stop is usually the lightest squark. Trigger Level Analysis (TLA) is a type of analysis that is performed using information from the trigger level which allows for higher event recording rate. TLA is needed, because all events coming from resonances with low masses cannot be recorded due to the large backgrounds. The goal of this project was to determine whether it is possible to use TLA for identifying stop pair production with four-jet final state. We investigated the possibility of separating all of the four jets at the trigger level. Three different cases with stop masses of 80 GeV, 150 GeV and 200 GeV were examined. We found that only a small fraction of generated events (less than 1% for each mass) can be identified as having four jets. Therefore, we need to investigate the scenario where the products of the stop decay merge into one jet because of the Lorentz boost.
