摘要：

I present first calculation of the branching fraction for the B-S(0) - (D) over bar K-0(s)0 decay by applying the QCD factorization approach, considering cross section final state interaction effects. Result of calculation shows that before the final particles to be produced, the D-(*) K+(*) mesons should be made, this intermediate state transition to the final state is done by exchanging one of the D-S((*)-) or pi(+) (p(+)) mesons. The numerical result of my calculation is B-S(0) - (D) over bar K-0(s)0 = (3.62 +/- 0.66) x 10(-4). The first observation of the B D K2 decay mode was reported by the LHCb collaboration. The branching fraction was measured by them to be B-S(0) - (D) over bar K-0(s)0 = (4.3 +/- 0.5(stat) f +/- 0.3(syst) +/- 0.3 (frag) +/- 0.6(norm)) x 10(-4). (C) 2017 Elsevier B.V.
