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 → Σ_c⁺⁺ + e^- + ν_e + π^- is calculated at the zero recoil point using this hybrid formalism.
