Multileptonic signals of co-annihilating left-right supersymmetric dark matter

We present a complete dark matter analysis of left-right supersymmetric scenarios that includes constraints from dark matter direct and indirect detection experiments. We concentrate on dark matter candidates which, while satisfying all constraints, are different from those of the minimal supersymmetric standard model. We consider in our analysis all possible co-annihilation channels relevant for setups in which several states are light and nearly degenerate, and devise a set of representative benchmark points satisfying all restrictions. We then study their consequent LHC signals, which exhibit promising multileptonic signatures that could consist, if observed, in a strong support for left-right supersymmetry.
