摘要：
Recently, the BESIII collaboration has reported an improved measurement of the branching fraction for D-0 -> K-pi(+)omega decay, the first observations and branching fraction measurements for D-0 -> K-S(0)pi(0)omega and D+ -> K-S(0)pi(+)omega decays with the values of (3.392 +/- 0.044(stat) +/- 0.085(syst))%, (0.848 +/- 0.046(stat) +/- 0.031(syst))%, and (0.707 +/- 0.041(stat) +/- 0.029(syst))%, respectively. In this work, we have obtained the non-resonant amplitudes under the factorization approach. The calculated values for branch ratios are B(D-0 -> K-pi(+)omega) =(3.302 +/- 0.195)%, B(D-0 -> K-S(0)pi(0)omega) = (0.782 +/- 0.067)%, and B(D+ -> K-S(0)pi(+)omega) = (0.702 +/- 0.111)% which are in good agreement with reported experimental values.
