Abstract
The original results for the baryon-pion couplings in the large Nc
QCD can be understood in a simpler way in the Hartree-Fock picture.
The large Nc relation and its 1/Nc correction between the heavy
baryon-meson coupling and the light baryon-meson coupling are emphasized.
Application to the baryon-
meson interactions is
straightforward. The implications of recent experimental result for the
strong coupling constants of the heavy baryon chiral Lagrangian are
discussed.
