Abstract:The meson production by mesons in the low-energy limit has been re-examined in the frame of static model of the extended source theory. Using Feynman's technique the calculation has been performed up to fifth order in the coupling constant. The renormalization procedure is the same as developed and applied by Chew in meson-nucleon scattering processes. To reduce the Feynman diagram an approximation similar to that of the T amm-Dancoff type has been used. The total cross section for charged and neutral pions fr… Show more
