Light-cone QCD sum rules are employed to compute the strong coupling constants: , and , where (B,B*) and (B0,B1) are negative and positive parity (0-,1-) and (0+,1+) doublets. The couplings are calculated both for finite values of the heavy quark mass and in the infinite heavy quark mass limit, deriving sum rules for .
