Contribution of the vector meson to the Υ(nS)→d¯*(2380)+X decay channel.

d*(2380) 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, Υ(nS)→d¯*(2380)+X, the contribution from the vector meson should also be considered. To this end, B* meson as an intermediate state in the Υ(nS)+d*(2380)→Υ(nS)+d*(2380) scattering is studied within the same framework of the SU(3) chiral quark model. As a result, it is shown that d¯* might be found in the momentum range of 0.3-0.9 GeV. [ABSTRACT FROM AUTHOR]
