What is the scale of new physics behind the $B$-flavour anomalies?
Motivated by the recent hints of lepton flavour non-universality in B-meson semi-leptonic decays, we study the constraints of perturbative unitarity on the new physics interpretation of the anomalies in $b \rightarrow c \ell \bar{\nu }$ and $b \rightarrow s \ell \bar{\ell }$ transitions. Within an e...
