We clarify open issues in relating low- and high-energy observables, at next-to-leading order accuracy, in models with a massive leptoquark embedded in a flavor nonuniversal SU(4)×SU(3)×SU(2)×U(1) gauge group. Extending previous work on this subject, we present a complete analysis of the O(αs) corrections to the matching conditions of semileptonic operators at the high scale. These corrections are not negligible, but they do not exceed the 10% level and are subleading compared to the O(α4…

The phenomenology of this model is considered in the context of the hints for lepton flavor universality violation in semileptonic B decays, and it is found that in b→sℓ^{+}⅓^{-} transitions, the observed deviations from the standard model predictions can be explained with natural values for the free parameters of the model.
