Abstract
The couplings in the Heavy Hadron Chiral theory Lagrangian from the QCD sum rules in an external axial field are estimated. Stability of the sum rules at moderate values of the Borel parameter is poor that probably signals slow convergence of the OPE series. At large values of the Borel parameter they stabilize, and yield the couplings much lower than the constituent quark model expectations. 18 refs.; 5 figs.
