Description

The presence of extra Yukawa couplings, in particular $\rho_{\tau\mu}$ and $\rho_{tu}$, can enhance $B \to \mu\bar\nu$ rate but leave $B \to \tau\bar\nu$ unchanged, thereby their ratio can deviate from the value common to the Standard Model and two Higgs doublet model type II. With recent hint of enhancement in $B \to \mu\bar\nu$ using full Belle data,the Belle II experiment could probe this New Physics with just a few ab$^{-1}$.
