Further study of f(0)(1710) with the coupled-channel approach and the hadron molecular picture

The f(0) (1710) was previously proposed to be a dynamically generated state with interactions between vector mesons. We extend the study of f(0) (1710) by including its coupling to channels of pseudoscalar mesons within the coupled-channel approach. The channels involved are K* (K) over bar*, rho rho, omega omega, phi phi, omega phi, pi pi, K (K) over bar, eta eta. We show that the pole assigned to f(0)(1710) does not change much. Then we calculate the partial decay widths of f(0) (1710) -> K*(K) over bar*->pi pi, K (K) over bar, eta eta as the coupled channel dynamically generated state as well as assuming it to be a pure K*(K) over bar* molecule. In both cases the ratios of partial decay widths agree fairly with that in PDG.
