T violation in ${\Lambda }_b\to \Lambda {\ell }^{+}{\ell }^{-}$ decays with polarized $\Lambda$

Abstract

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.
