First Measurement of the Absolute Branching Fraction of $Λ \to p μ^{-} ν ˉ_{μ}$

M. Ablikim, M. N. Achasov, P. Adlarson +504

The absolute branching fraction of $Λ \to p μ^{-} ν ˉ_{μ}$ is reported for the first time based on an $e^{+} e^{-}$ annihilation sample of ten billion $J / ψ$ events collected with the BESII…
