The [1,2] Padé Amplitudes for $π π$ Scatterings in Chiral Perturbation Theory

Guang-You Qin, W. Z. Deng, Z. G. Xiao +1

A detailed analysis to the [1,2] Padé approximation to the $π π$ scattering 2--loop amplitudes in chiral perturbation theory is made.

The Constraints of Unitary on $π π$ Scattering Dispersion Relations

Jianyang He, Z. G. Xiao, H. Q. Zheng

A new dispersion relation for the partial wave $π π$ scattering $S$ matrix is set up. Using the dispersion relation we generalize the single channel unitarity condition, $S S^{+} = 1$ , t…
