Decay of heavy-light hybrids in HQET sum rules

The decay widths of the 0(++) and 1(-+) heavy-light, hybrids to B(D) and pion are calculated by using the QCD sum rules. The interpolated current of the hybrid is chosen as gamma(alpha)G(alpha mu)(a)T(a)h(upsilon)(x). In order to simplify the calculation and avoid the ambiguity of the three-point correlation unction, a two-point correlation function between the pion and vacuum is used instead. The decay width of the 0(++)-->B(D) is about 12(16) MeV, while the 1(-+)-->B(D) is around 0.4(1.8) MeV. We keep the leading-order of 1/M-Q expansion in our calculation for convenience.
