We have investigated ̅ ̅ 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 model. We have found that there is appreciable difference between the standard model and model predictions. Recently, the lepton flavour non-universality parameters and 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 and 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 and could be achieved in non-universal model considering the new physics couplings to muon sector only.
