Semileptonic b-baryon decays within a new physics approach
Abstract The excess in the measurement of the branching fractions of $$\bar{B}\rightarrow D(D^*){\tau }^- \bar{\nu }_{\tau }$$ B ¯ → D ( D ∗ ) τ - ν ¯ τ and $$B_{c}\rightarrow J/\psi {\tau }^{-} \bar{\nu }_{\tau }$$ B c → J / ψ τ - ν ¯ τ from the standard model expectation hints the existence of new...
