Disentangling Lepton Flavour Universal and Lepton Flavour Universality Violating Effects in $b\to s{\ell }^{+}{\ell }^{-}$ Transitions

Marcel Algueró, Bernat Capdevila, Andreas Crivellin +1

In this letter we propose a strategy for discerning if new physics in the Wilson coefficient ${\mathcal{C}}_{9\mu }$ is dominantly lepton flavour universality violating or if it contains a…
