The study of sq_L sq_L production at LHC in the l^\pm l^\pm channel and sensitivity to other models

Abstract

${\tilde{q}}_L{\tilde{q}}_L$ production is one of the main SUSY production processes in the MSSM, which occurs due to the chirality flip caused by the Majorana gluino mass. This process is one of the sources of same sign two lepton (SS2$l$) events, however, gluino production also contributes to this channel. In this paper, we develop a method to identify gluino and squark production separately in the SS2$l$ channel, based on cuts on the kinematical configuration of the jets. We applied the method to the MSSM, a model with an extended gluino sector, and the Littlest Higgs model with T-parity (LHT), and found a distinctive difference between these models when considering the numbers of SS2$l$ events selected by the cuts.
