Measurement of the Absolute Branching Fraction for $Λ_{c}^{+} \to Λ μ^{+} ν_{μ}$

M. Ablikim, M. N. Achasov, S. Ahmed +424

We report the first measurement of the absolute branching fraction for $Λ_{c}^{+} \to Λ μ^{+} ν_{μ}$ . This measurement is based on a sample of $e^{+} e^{-}$ annihilation data at a center…
