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

Chuan-Hung Chen, C. Q. Geng, J. N. Ng

We examine the T-odd transverse lepton and $\Lambda$ polarizations in the baryonic decays of ${\Lambda }_b\to \Lambda l^{+}{l}^{-}(l=e,\mu )$ to study the T violating effects. We show that the lepton polarizati…
