Probing CP Violation with and without Momentum Reconstruction at the LHC

Understand

We study the potential to observe CP-violating effects in SUSY cascade decay chains at the LHC.

• We consider squark and gluino production followed by subsequent decays into neutralinos with a three-body leptonic decay in the final step.
• Asymmetries composed by triple products of momenta of the final state particles are sensitive to CP-violating effects.
• Due to large boosts these asymmetries can be difficult to observe at a hadron collider.
