Abstract
Recently, the BESIII collaboration has reported an improved measurement of the branching fraction for D 0 → K − π + ω decay, the first observations and branching fraction measurements for D0→KS0π0ω and D+→KS0π+ω 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(D0→K−π+ω)=(3.302±0.195)% , B(D0→KS0π0ω)=(0.782±0.067)% , and B(D+→KS0π+ω)=(0.702±0.111)% which are in good agreement with reported experimental values.
