A DISCUSSION ON THE NON-PERTURBATIVE EFFECTS IN MESON WAVE FUNCTIONS

  • We apply the background field method to calculate the operator expansion of the two-piont correlation function related to the moments of meson distribution amplitude. It is shown that the non-pertur bative effects depend in detail on the meson helicity and quark mass.

Abstract: We apply the background field method to calculate the operator expansion of the two-piont correlation function related to the moments of meson distribution amplitude. It is shown that the non-pertur bative effects depend in detail on the meson helicity and quark mass.
