Study of D* Polarization to Discriminate New Physics in (formula presented)

Recent LHCb result shows a clear confirmation of excess in (formula presented) and an indication of lepton flavor non-universality. Here we have studied angular observable (formula presented) polarization fraction, (formula presented), in (formula presented). We find that (formula presented) can be a good discriminant of new physics operators provided their Lorentz structure is different from the standard model operator. For the values of new physics (NP) couplings which provide good fit to (FORMULA PRESENTED), (formula presented) and (formula presented) spectra, (formula presented) provides good discrimination for three of the allowed solutions.
