The lepton universality violating flavor ratios indicate new physics either in or in or in both. If the new physics is only transition, the corresponding new physics operators, in principle, can have any Lorentz structure. In this work, we perform a model independent analysis of new physics only in decay by considering effective operators either one at a time or two similar operators at a time. We include all the measurements in sector along with in our analysis. We show that various new physics scenarios with vector/axial-vector operators can account for data but those with scalar/pseudoscalar operators and with tensor operators can not. We also show that the azimuthal angular observable in decay is most suited to discriminate between the different allowed solutions.
