The effect of supersymmetric cp phases on q(q)over-bar annihilations into charginos and neutralinos

Abstract

We compute the rates for q(q) over bar annihilation into charginos and neutralinos by taking into account the effects of supersymmetric soft phases. In particular, the phase of the p parameter gains direct accessibility via the production of dissimilar charginos and neutralinos. The phases of the trilinear soft masses do not have a significant effect on the cross-sections. Our results can be important for sparticle searches at the LHC.
