${\Lambda }_b\to \Lambda {\ell }^{+}{\ell }^{-}$ and ${\Lambda }_b\to {\Lambda }^{\ast }{\ell }^{+}{\ell }^{-}$ decays with polarized leptons

Diganta Das, Vedant Parekh, Ria Sain +1

We present an analysis of lepton polarization observables in the rare flavor-changing neutral current decays ${\Lambda }_b\to \Lambda {\ell }^{+}{\ell }^{-}$ and ${\Lambda }_b\to {\Lambda }^{\ast }{\ell }^{+}{\ell }^{-}$. These decays are…
