Abstract

We present the results on the relativistic six-pion scattering amplitude at low energy, calculated at O(p 4 ) within the framework of the massive O(N) nonlinear sigma model extended to the next-to-leading order in the chiral counting. For N = 3, 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 N (meson) flavors at O(p 4 ).
