Title: B-decay anomalies in a composite leptoquark model

Here, the collection of a few anomalies in semileptonic B-decays, especially in b → cτ$$\overline{v}$$, invites speculation about the emergence of some striking new phenomena, perhaps interpretable in terms of a weakly broken U(2) n flavor symmetry and of leptoquark mediators. We aim at a partial UV completion of this interpretation by generalizing the minimal composite Higgs model to include a composite vector leptoquark as well.
