Discriminating 1D new physics solutions in b → sℓℓ decays

The recent measurements of [equation presented] a set of CP-averaged angular observables for [equation presented] the decay and its isospin partner [equation presented] by the LHCb Collaboration consistently hint at lepton universality violation in b→ sℓℓ the transitions. In this work, we first perform global fits to the data and show that five one-dimensional scenarios, i.e, [equation presented] and [equation presented] can best explain the so-called B anamolies. Furthermore, we explore how these scenarios can be distinguished from each other. For this purpose, we first study the combinations of four angular asymmetries and find that they cannot distinguish the five new physics scenarios. We then show that a newly constructed ratio RS can uniquely discriminate the five new physics scenarios in proper intervals of if q2 it can be measured with percent-level precision.
