Abstract
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)
