| Abstract | We study dynamically generated a(0) 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 1-channel exchanged mesons for calculating interactions between vector mesons. Analogous to a(0) (980) as a K (K) over bar-pi eta dynamically generated state, there is an a(0)(1710) as a coupled channel dynamically generated state near K*(K) over bar* threshold. The channels involved are rho phi, K*(K) over bar*, rho omega, K (K) over bar, pi eta. This a(0) mainly decays to rho omega, pi eta and K (K) over bar. This pole is much tied to the coupled channel effect. If we turn off either rho phi or K*(K) over bar*, the pole disappears. In addition, it is found that a(0)(1450) may also be dynamically generated by rho omega interactions due to pi and eta exchange. |
