Investigations on the Property of $f_0(600)$ and $f_0(980)$ Resonances in $\gamma \gamma \to \pi \pi$ Process

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

Using dispersion relation technique and experimental data, a coupled channel analysis on $\gamma \gamma \to \pi \pi$ process is made. Di-photon coupling of $f_0(600)$ and $f_0(980)$ resonances are e…
