Two dynamical generated [Formula omitted] resonances by interactions between vector mesons
We study dynamically generated [Formula omitted] resonances by interactions between vector mesons including their coupling to channels of pseudoscalar mesons within coupled-channel approach. Both vector and pseudoscalar mesons are considered as t-channel exchanged mesons for calculating interactions...

| Summary: | We study dynamically generated [Formula omitted] resonances by interactions between vector mesons including their coupling to channels of pseudoscalar mesons within coupled-channel approach. Both vector and pseudoscalar mesons are considered as t-channel exchanged mesons for calculating interactions between vector mesons. Analogous to [Formula omitted] as a [Formula omitted] dynamically generated state, there is an [Formula omitted] as a coupled channel dynamically generated state near [Formula omitted] threshold. The channels involved are [Formula omitted]. This [Formula omitted] mainly decays to [Formula omitted], [Formula omitted] and [Formula omitted]. This pole is much tied to the coupled channel effect. If we turn off either [Formula omitted] or [Formula omitted], the pole disappears. In addition, it is found that [Formula omitted] may also be dynamically generated by [Formula omitted] interactions due to [Formula omitted] and [Formula omitted] exchange. |
