Studies on $π^{+} π^{-}$ phase motion in the $Ψ^{'} \to J /Ψ π^{+} π^{-}$ process

Z. X. Zhang, J. J. Sanz-Cillero, X. Y. Shen +3

We propose a measurement on the elastic $π π$ scattering phase shift difference $δ_{0}^{0} - δ_{0}^{2}$ through $Ψ^{'} \to J /Ψ π^{+} π^{-}$ process in future high statistics BES-III experiment. The de…

Direct measurement of the absolute branching fraction for $D^{+} \to K ˉ^{0} μ^{+} ν_{μ}$ and determination of $Γ (D^{0} \to K^{-} μ^{+} ν_{μ}) /Γ (D^{+} \to K ˉ^{0} μ^{+} ν_{μ})$

M. Ablikim

The absolute branching fraction for the decay $D^{+} \to K ˉ^{0} μ^{+} ν_{μ}$ is determined using $5321 \pm 149 \pm 160$ singly tagged $D^{-}$ sample from the data collected around 3.773 G…
