Implication of family non-universal $Z^{\prime }$ model to rare exclusive $b\to s(l\bar{l},\nu \bar{\nu })$ transitions

Abstract

We have investigated $B\to (K,K^{\ast })(l\bar{l},\nu \bar{\nu })$ decay channels and predicted some form factor dependent observables (e.g. branching ratio, forward-backward asymmetry and lepton polarization asymmetry) considering new physics contribution from non-universal $Z^{\prime }$ model. We have found that there is appreciable difference between the standard model and $Z^{\prime }$ model predictions. Recently, the lepton flavour non-universality parameters $R_K$ and $R_{K^{\ast }}$ have been measured by the LHCb collaboration and are found to be different from their standard model predictions. These deviations provide the hint of flavor non-universality in lepton sector and motivate our research to look for new physics beyond the standard model. The $R_K$ and $R_{K^{\ast }}$ anomalies may be due to new physics in either electron or muon sector or both. In our work, we have shown that the experimental results of $R_K$ and $R_{K^{\ast }}$ could be achieved in non-universal $Z^{\prime }$ model considering the new physics couplings to muon sector only.
