Three-body decays of Ds+ → η(η′)π+π0

Abstract

In this paper, we investigate the three-body decays of [Formula: see text] meson to [Formula: see text] and [Formula: see text] final state mesons, using a simple model based on the framework of the factorization approach. As we know, there are tree and emission-annihilation diagrams for these decay modes in the factorization approach. We calculate the total [Formula: see text] and [Formula: see text] branching ratios, including the nonresonant and resonances contributions, and in view of the [Formula: see text] mixing, by applying the Dalitz plot analysis and obtain [Formula: see text] and [Formula: see text], while the experimental values are [Formula: see text] and [Formula: see text], respectively. The branching ratios obtained in our model are partly compatible with the experimental results.
