By extending and making more precise the content of Barbieri et al. (Eur Phys J C 77(1):8, 2017), we describe one such attempt based on the Pati–Salam SU(4) group, that unifies colour and the B-L charge, in the context of a new strongly interacting sector, equally responsible for producing a pseudo-Goldstone Higgs boson.

Addressing the B-physics anomalies in a fundamental Composite Higgs model (2018, background): “Alternatively, U 1 could arise as a composite vector resonance of a new strongly coupled sector lying at the TeV scale [33, 52, 53].”
Revisiting the vector leptoquark explanation of the B-physics anomalies (2019, background): “Given the success of some EFT approaches and simplified models in describing available data, the attention has shifted recently towards the development of more complete (and more complex) models with a consistent ultraviolet (UV) behavior (see in particular [28–42]).”
B-decay discrepancies after Moriond 2019 (2019, methodology): “Explaining the data by a single mediator: the U1 leptoquark solution The only single mediator that can yield non-zero values for [C (1) lq ]3323 = [C (3) lq ]3323 and [C (1) lq ]2223 = [C (3) lq ]2223 is the U1 vector leptoquark [35,37,38,40,81–92], which transforms as (3,1)2/3 under the SM gauge gr”
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].”
