Description
We study three-body systems \eta K^ \bar{K}^, \pi K^ \bar{K}^ and K K^ \bar{K}^ by Faddeev fixed-center approximation. Under fixed-center approximation framework, we can view a three-body system as a cluster which is generated by two particles in system and the third particle, where we view K^ \bar{K}^cluster as f_0(1710), a_0(1710) and f_2’(1525), respectively, and scatter \eta, \pi and K on K^ \bar{K}^. In module squared amplitude of three-body systems, we find \eta(2100) , \pi(2070) and \eta_2(1780) for \eta K^ \bar{K}^, \eta(2100), \pi(2070) and \pi _2(1880) for \pi K^ \bar{K}^ and several new states for K K^ \bar{K}^. Our results offer some new views for some further states and exotic states.
