AbstractThe radiative decay B-q(*) --> B(q)gamma (q = u, d or s) is re-examined using a modified light-cone quantum chromodynamics (QCD) sum rule method. In this method, adequate chiral operators are chosen as the interpolating fields in the correlators used for a sum rule estimate of the relevant coupling g(Bq)(Bq)(*)gamma. Besides showing the physical picture consistent with the underlying physics in B-q(*) --> B(q)gamma, the resulting sum rule can effectively avoid the pollution by the nonlocal matrix element (gamma(q)\(q) over bar (x)gamma(mu)gamma(5)q(0)\0> starting with twist-3, about which little is known. Also, a comparison is made with the previous results from light-cone QCD sum rules and chiral perturbation theory.
