Positivity constraints on LECs of $χ$ PT lagrangian at $\cO(p^6)$ level

Zhi-Hui Guo, Ou Zhang, H. Q. Zheng

Positivity constraints on the LECs of $\cO(p^6)$ $χ$ PT lagrangian are discussed. We demonstrate that the constraints are automatically satisfied inside the Mandelstam triangle for…

Investigations on the Property of $f_{0} (600)$ and $f_{0} (980)$ Resonances in $γ γ \to π π$ Process

X. G. Wang, O. Zhang, L. C. Jin +2

Using dispersion relation technique and experimental data, a coupled channel analysis on $γ γ \to π π$ process is made. Di-photon coupling of $f_{0} (600)$ and $f_{0} (980)$ resonances are e…

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…
