CP asymmetries in the supersymmetric trilepton signal at the LHC

Understand

In the CP-violating Minimal Supersymmetric Standard Model, we study the production of a neutralino-chargino pair at the LHC.

• For their decays into three leptons, we analyze CP asymmetries which are sensitive to the CP phases of the neutralino and chargino sector.
• We present analytical formulas for the entire production and decay process, and identify the CP-violating contributions in the spin correlation terms.
• This allows us to define the optimal CP asymmetries.
