We present a new observable sensitive to a certain combination of CP violating phases in supersymmetric extensions of the Standard Model, viz. a triple product of momenta in the cascade decay of a heavy squark via an on-shell neutralino and off-shell slepton. We investigate the regions of parameter space in which the signal is strong enough to be detectable at the LHC with ∼ (102-103)/sin 2(2Δ) identified events, where Δ is a certain combination of phases in the MSSM presented in the text.
