CHIRAL DIVERGENT PROPERTIES OF HADRONS IN THE LARGE N-C LIMIT

We compute the leading non-analytic correction to the baryon mass in t he combined limits m(pi) --> O, N-c --> infinity with m(pi)N(c) held f ixed. We reproduce the results of Cohen and Broniowski using semiclass ical methods rather than heavy-baryon chiral perturbation theory. The calculation is organized to demonstrate: 1 the model independence of o ur results; and 2 the crucial role played by (iso)rotations of the hed gehog pion cloud surrounding the baryon. Our rotationally improved lar ge-N-c calculation yields results that naturally interpolate between o rdinary chiral perturbation theory on the one hand, and large-N-c phys ics on the other.
