Abstract We present a three-site Pati–Salam gauge model able to explain the Standard Model flavor hierarchies while, at the same time, accommodating the recent experimental hints of lepton-flavor non-universality in B decays. The model is consistent with low- and high-energy bounds, and predicts a rich spectrum of new states at the TeV scale that could be probed in the near future by the high- p T experiments at the LHC.

- Review of lepton universality tests in B decays (2018, background): “Stringent bounds coming from light-quark processes require different couplings of the leptoquark to the different generations, leading to the introduction of a Pati-Salam gauge group for each of the three generations [207,224–228].”
- B-decay discrepancies after Moriond 2019 (2019, methodology): “This puts some tension on models based on a U(2)q flavour symmetry [37, 83, 87, 89], where the natural expectation for the size of g32 lq g33 lq is |Vcb| ≈ 0.”
