Charged-Higgs on $$R_{D^{(*)}}$$ R D ( ∗ ) , $$\tau $$ τ polarization, and FBA

Abstract We study the influence of a charged-Higgs on the excess of branching fraction ratio, $$R_M = BR(\bar{B} \rightarrow M \tau \bar{\nu }_\tau )/BR(\bar{B} \rightarrow M \ell \bar{\nu }_\ell )$$ R M = B R ( B ¯ → M τ ν ¯ τ ) / B R ( B ¯ → M ℓ ν ¯ ℓ ) $$(M=D, D^*)$$ ( M = D , D ∗ ) , in a generi...
