Semiclassical Meson-Baryon Dynamics from Large-Nc QCD
The large- limit of the meson-baryon effective Lagrangian is shown to
reduce to a semiclassical field theory. A chiral bag structure emerges
naturally in the limit. A possible connection between
the chiral bag picture and the Skyrme model is discussed. The classical
meson-baryon theory is used to reproduce the non-analytic correction
to the baryon mass obtained previously as a loop correction in chiral
perturbation theory.Comment: (13 pages, 1 figure, uses harvmac and uufiles), UCSD/PTH 94-1
