Abstract
was observed by WASA-at-COSY collaborations in the nuclear reaction recently. Its particularly narrow width may indicate the new QCD-allowed hadronic structure. To further confirm the existence of this peculiar particle in a totally different kind of reaction, , the contribution from the vector meson should also be considered. To this end, meson as an intermediate state in the scattering is studied within the same framework of the SU(3) chiral quark model. As a result, it is shown that might be found in the momentum range of 0.3–0.9 GeV.
