摘要：
In this work, we study systems composed of a (Formula presented.) and (Formula presented.) meson pair. We find three bound states in isospin, spin-parity channels (Formula presented.) , (Formula presented.) , and (Formula presented.). The state with (Formula presented.) can be a good candidate for the (Formula presented.). We also study the (Formula presented.) system, and a bound state with mass 5728 MeV and width around 20 MeV is obtained, which can be identified with the (Formula presented.) resonance. In the case of (Formula presented.) , one obtains repulsion and, thus, no exotic (molecular) mesons in this sector are generated in the approach. © 2016, The Author(s).
