Abstract

We examine the T-odd transverse lepton and Λ\Lambda polarizations in the baryonic decays of ΛbΛl+l(l=e,μ)\Lambda_b\to\Lambda l^+l^- (l=e ,\mu) to study the T violating effects. We show that the lepton polarizations are suppressed but the Λ\Lambda ones can be as large as 50% in CP violating theories beyond the standard model such as the SUSY models, which can be tested in various future hadron colliders.
