Pole analysis on unitarized $SU(3)\times SU(3)$ one loop $\chi$PT amplitudes

L. Y. Dai, X. G. Wang, H. Q. Zheng

We analyze $\pi \pi -K\bar{K}$ and $\pi \eta -K\bar{K}$ couple channel [1,1] matrix Padé amplitudes of $SU(3)\times SU(3)$ chiral perturbation theory. By fitting phase shift and inelasticity da…
