SUSY CP phases and asymmetries at colliders

Understand

In the Minimal Supersymmetric Standard Model, physical phases of complex parameters lead to CP violation.

• We show how triple products of particle momenta or spins can be used to construct asymmetries, that allow us to probe these CP phases.
• To give specific examples, we discuss the production of neutralinos at the International Linear Collider.
• For the Large Hadron Collider, we discuss CP asymmetries in squark decays, and in the tri-lepton signal.
