Resonance and nonresonant contributions to three-body Ds+→π+π0η′ decay

The [Formula: see text] decay has been observed nonresonant as well as through [Formula: see text] resonances. The experimental values of its branching ratio are [Formula: see text] for nonresonant process and [Formula: see text] for nonresonant and resonance phases together, which are tabulated by Particle Data Group (PDG) collaboration. Recently, the BESIII collaboration has reported a measurement of the branching fraction for [Formula: see text] decay with the value of [Formula: see text]. In this work, we have presented an analysis of the branching fraction for this decay that has been calculated under the factorization approach. We have obtained the resonance and nonresonant amplitudes with annihilation corrections in our computation. Our result for the nonresonant branching ratio is [Formula: see text], which is comparable to the experimental result of PDG collaboration. Considering the nonresonant and resonance contributions, the theoretical value of the branching ratio is [Formula: see text], which is in agreement with the reported experimental value.
