arXiv:1901.10169 · doi:10.1103/PhysRevD.99.096014
Abstract
The scattering has been studied by two groups which both claimed a dynamical generated scalar meson, most likely to be . Here we investigate the influence of coupled-channels of pseudoscalar mesons, i.e., and , on this dynamical generated scalar state. With the coupled channel effect included, the pole and partial decay widths are found to be more close to PDG values for .
