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