Analyses of pion-nucleon elastic scattering amplitudes up to $O (p^{4})$ in extended-on-mass-shell subtraction scheme

Yun-Hua Chen, De-Liang Yao, H. Q. Zheng

We extend the analysis of elastic pion-nucleon scattering up to $O (p^{4})$ level using extended-on-mass-shell subtraction scheme within the framework of covariant baryon chiral pertu…

A Dispersive Analysis on the $f_{0} (600)$ and $f_{0} (980)$ Resonances in $γ γ \to π^{+} π^{-}, π^{0} π^{0}$ Processes

Yu Mao, Xuan-Gong Wang, Ou Zhang +2

We estimate the di-photon coupling of $f_{0} (600)$ , $f_{0} (980)$ and $f_{2} (1270)$ resonances in a coupled channel dispersive approach. The $f_{0} (600)$ di-photon coupling is also reinvest…

Ambiversion of X(3872)

Ou Zhang, C. Meng, H. Q. Zheng

An analysis including most recent Belle data on X(3872) is performed, using coupled channel Flatté formula. A third sheet pole close to but \textit{below} $D^{0} D^{* 0}$ threshold is…

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…
