The lepton universality violating flavor ratios RK/RK� indicate new physics either in b�sμ+μ� or in b�se+e� or in both. If the new physics is only b�se+e� 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 b�se+e� decay by considering effective operators either one at a time or two similar operators at a time. We include all the measurements in b�se+e� sector along with RK/RK� in our analysis. We show that various new physics scenarios with vector/axial-vector operators can account for RK/RK� data but those with scalar/pseudoscalar operators and with tensor operators can not. We also show that the azimuthal angular observable P1 in B�K�e+e� decay is most suited to discriminate between the different allowed solutions. © 2021 The Author(s)
