英文摘要	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.
