Impact of $Z^{\prime }$ and UED parameters on different asymmetries in $B_s\to \varphi {\ell }^{+}{\ell }^{-}$ decays

Abstract

A comprehensive study of the impact of new-physics on different observables for $B_s\to \varphi {\ell }^{+}{\ell }^{-}$ has been done. We examine the new physics models such as $Z^{\prime }$ and UED models, where the effects of new physics coming through the modification of Wilson coefficients. We have analyzed these effects through the theoretical prediction of the branching ratio, the forward-backward asymmetry, lepton polarization asymmetries and the helicity fractions of the final state meson. These all observables will definitely be measured in present and future colliders with great precision. We also pointed out that hadronic uncertainties in various physical observables are small which make them an ideal probe to establish new physics. Therefore, the measurements of these observables for the same decay would permit the detection of physics beyond the Standard Model and will also help us to distinguish between different new physics scenarios.
