Abstract: The radiate decay B^*_d→B_dγ was studi ed with the improved light-cone QCD summation rules method in which adequate chiral current operators are chosen in the correlation function used for calculation of the coupling constantgB^*_dB_dγ, eliminating completely the effect from the uncertainty of the matrix element 〈γ(q)|(x)γ_μγ ₅d(0)| 0〉. The decay width is agreement with the result of standard light-cone QCD sum rules in the range of error margin.

Key words: improved light-cone QCD sum rules, radiate decay, deca y width
