In the context of simulation and reconstruction for the Muon Collider, muon reconstruction efficiency has been evaluated to explore the potential for the study of dark-SUSY channels. In dark-SUSY models, supersymmetric particles act as a portal between Standard Model particles and the dark sector. In this analysis, the lightest Minimal Supersymmetric Standard Model neutralino decays, on one hand, directly in a dark photon or, on the other hand, in two dark photons through a dark Higgs boson. A muon pair, with kinematics driven by photon mass, is then expected from each dark photon. Therefore, the final state is characterized by four muons in one channel and eight muons in the other. Preliminary results of the muon reconstruction performance are shown for a possible range of neutralino and dark photon masses at a centre of mass energy of 3 TeV for the time being without the effects of the machine Beam-induced Background.
