摘要：The couplings between the soft pion and the doublet of heavy-light mesons are basic parameters of the ChPT approach to the heavy-light systems. We compute the unquenched (Nf =2) values of such couplings in the static heavy quark limit: (1) bg, coupling to the lowest doublet of heavy-light mesons, and (2) eg, coupling to the rst orbital excitations. A brief description of the calculation together with the short discussion of the results is presented.
