Abstract
The rare decay $B \to K^{\ast}\ell^{+}\ell^{−}$ is a very significant mode to search for physics beyond the Standard Model (SM). The mode provides a very rich spectrum of observables obtained from the angular distribution ofits decay products. The recent LHCb measured values of these observables are used to conclude an evidence of right-handed currents at the kinematic endpoint of this decay mode. As the conclusion is drawn at the maximum dilepton invariant mass square $(q^2)$ kinematic endpoint, it relies only on heavy quark symmetries where it is valid without significant corrections.
