B-decay anomalies in a composite leptoquark model

The collection of a few anomalies in semileptonic B-decays, especially in \(b\rightarrow c \tau \bar{\nu }\), invites to speculate 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. Here 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.
