CHIRAL EFFECTIVE ACTION WITH HEAVY-QUARK SYMMETRY

We derive an effective action combining chiral and heavy-quark symmetr y, using approximate bosonization techniques to QCD-inspired models of spontaneous symmetry breaking. We explicitly show that the heavy-quar k limit is compatible with the large N(c) (number of color) limit in t he meson sector, and estimate the couplings between the light and heav y mesons (D, D,...) and their chiral partners to order one in the hea vy-quark mass. The relevance of this effective action to solitons with heavy quarks is briefly discussed.
