摘要：

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 LAMBDA(b)0-->SIGMA(c)++ + e- + nu(e)BAR + pi- is calculated at the zero recoil point using this hybrid formalism.
