Abstract
Abstract
Based on BESIII measurements of the reaction
, we investigate this process by considering the S-wave pseudoscalar-pseudoscalar interaction within the unitary chiral approach and the contributions from the intermediate resonances
and
. Our calculation can reasonably reproduce the experimental data, and our results imply that
, which is dynamically generated from the S-wave pseudoscalar-pseudoscalar interaction, plays an important role in this process, and the contributions from the intermediate resonances
and
are also necessary. More precise measurements of this process in future can shed light on the nature of
and
