Stable massive particle in the ATLAS high-level muon trigger

Charged stable massive particles (SMPs) which are predicted by theories beyond the Standard Model, may be produced at the Large Hadron Collider (LHC) built at CERN. Algorithms to trigger such particles with the ATLAS detector at the LHC have been developed. According to studies with Monte Carlo samples, the algorithms are expected to trigger such particles with high efficiency in the velocity region of beta > 0.5.
