Reinterpreting the results of the search for long-lived charged particles in the pMSSM and other BSM scenarios

The CMS search for long-lived charged particles in pp collisions at $\sqrt{s}$ = 7 and 8 TeV sets the most stringent limits existing to date on long-lived leptons. It is challenging to reinterpret these results under different model assumptions due to the complex dependence of the signal acceptance on the kinematic properties of the long-lived particles predicted by these models. This note presents a reinterpretation technique that overcomes this challenge by estimating the signal acceptance using tabulated efficiency values that are a function of the kinematics of individual long-lived particles. The proposed technique is used to extend a previous CMS pMSSM reinterpretation to the case of long-lived charginos.
