First Observation of the Direct Production of the $χ_{c 1}$ in $e^{+} e^{-}$ Annihilation

BESIII Collaboration

We study the direct production of the $J^{P C} = 1^{++}$ charmonium state $χ_{c 1} (1 P)$ in electron-positron annihilation by carrying out an energy scan around the mass of the $χ_{c1}(…

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…
