Y and ψ leptonic decays as probes of solutions to the R(D (*)) puzzle

Abstract Experimental measurements of the ratios R D ∗ ≡ Γ B → D * τ v Γ B → D * ℓ v ℓ = e , μ $$ R\left({D}^{\left(\ast \right)}\right)\equiv \frac{\Gamma \left(B\to {D}^{\left(*\right)}\tau v\right)}{\Gamma \left(B\to {D}^{\left(*\right)}\ell v\right)}\left(\ell =e,\mu \right) $$ show a 3.9σ devia...
