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…

Dynamical Properties of the $σ$ Meson

H. Q. Zheng

Studies on the dynamical properties of the $σ$ meson are reviewed and discussed. The important role of fundamental principles such as analyticity, unitarity and crossing symmetry p…

On the scalar nonet in the extended Nambu Jona-Lasinio model

Ming-Xian Su, L. Y. Xiao, H. Q. Zheng

We discuss the lightest scalar resonances, $f_{0} (600)$ , $κ (800)$ , $a_{0} (980)$ and $f_{0} (980)$ in the extended Nambu Jona-Lasinio model. We find that the model parameters can be tuned,…

Precison Measurements of the Mass, the Widths of $ψ (3770)$ Resonance and the Cross Section $σ [e^{+} e^{-} \to ψ (3770)]$ at $E_{cm} = 3.7724$ GeV

M. Ablikim et al.

By analyzing the $R$ values measured at 68 energy points in the energy region between 3.650 and 3.872 GeV reported in our previous paper, we have precisely measured the mass, the t…
