Lepton flavor universality violation without new sources of quark flavor violation

We show that new physics models without new flavor violating interactions can explain the recent anomalies in the b→sℓ+ℓ- transitions. The b→sℓ+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.
