b → cτ ν ¯ $$ \overline{\nu} $$ e,μ contributions to R(D(*))

Abstract The R(D (*)) puzzle stands for a ~ 3σ violation of lepton flavor universality between the decay rates of B → D (*) τν and B → D (*) ℓν, where ℓ = e, μ. If it is accounted for by new physics, there is no reason in general that the relevant neutrinos are, respectively, ν τ and ν ℓ . We study...
