    88== Model Description ==
     9The model is based on MSSM, but adding a dark sector. The dark sector, ''U(1)D'', is broken, giving rise to light dark photons (''γD'') that weakly couple to the SM particles via a small kinetic mixing with photons. The lightest neutralino ''n1'' in MSSM is no longer stable and can decay via processes such as ''n1 → nD + γD'', where ''nD'' is a light dark neutralino (fermion). In this model, the ''γD'' is mediated by very weak interactions with the SM, and can decay to muon pairs promptly or non-promptly.
