Non-abelian gauge extensions for B-decay anomalies
We study the generic features of minimal gauge extensions of the Standard Model in view of recent hints of lepton-flavor non-universality in semi-leptonic b→sℓ+ℓ− and b→cℓν decays. We classify the possible models according to the symmetry-breaking pattern and the source of flavor non-universality. W...
