Abstract
We present the results on the relativistic six-pion scattering amplitude at low energy, calculated at within the framework of the massive nonlinear sigma model extended to the next-to-leading order in the chiral counting. For , this approach corresponds to the two(-quark)-flavor Chiral Perturbation Theory. We also present the expressions for the pion mass, pion decay constant and the four-pion amplitude in the case of (meson) flavors at .
