摘要

We study the T violating effects in the baryonic decays of $\Lambda_b\to\Lambda l^+l^- (l=e ,\mu)$ with polarized $\Lambda$ . We show that the transverse $\Lambda$ polarizations in these baryonic decays could 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.
