Asymmetries and observables for ${\Lambda }_b\to \Lambda {\ell }^{+}{\ell }^{-}$

Abstract

The semi-leptonic baryonic $b\to s$ decay, ${\Lambda }_b\to \Lambda {\ell }^{+}{\ell }^{-}$, has been studied and new angular observables and asymmetries have been proposed which can test the presence of new physics beyond the standard model.
