Title: Relativistic chiral quark model for pseudoscalar emission from heavy mesons

The amplitudes for one-pion mediated transitions between heavy meson excited states are obtained in the framework of the relativistic chiral quark model. The effective coupling constants to pions and the decay widths of excited heavy mesons with l{le}2 for non-radially excited, and the l=0 radially excited mesons are presented for both charmed and {ital b}-flavored mesons. We also discuss the allowed decays of strange excited heavy mesons by emission of a {ital K} meson. {copyright} {ital 1999} {ital The American Physical Society}
