Title: Lepton flavor universality violation without new sources of quark flavor violation

Abstract

We show that new physics models without new flavor violating interactions can explain the recent anomalies in the b → s ℓ + ℓ - transitions. The b → s ℓ + ℓ - arises from a Z ' penguin which automatically predicts the V - A structure for the quark currents in the effective operators. This framework can either be realized in a renormalizable U (1)' setup or be due to new strongly interacting dynamics. The dimuon resonance searches at the LHC are becoming sensitive to this scenario since the Z ' is relatively light, and could well be discovered in future searches by ATLAS and CMS.
