Chiral perturbation theory for hadrons containing a heavy quark: the sequel

Abstract

Charm and bottom mesons and baryons are incorporated into a low energy chiral Lagrangian. Interactions of the heavy hadrons with light octet Goldstone bosons are studied in a framework which represents a synthesis of chiral perturbation theory and the heavy quark effective theory. The differential decay rate for the semileptonic process $\LBzero \to \Sigma_c^{++} + e^- + \bar{\nu}_e + \pi^-$ is calculated at the zero recoil point using this hybrid formalism.
