Abstract

In the present work, we construct the Lagrangians including three-meson, meson-diquark-antidiquark vertices, such that the diquark-antidiquark component as well as the molecular component are introduced within the effective field theory. With the obtained effective potentials projecting to spin 0, 1 and 2, we solve the Bethe-Salpeter equation with the on-shell approximation, and find that X(4500) can be explained as the mixture of components Ds*+Ds*-, AcqAcq and AcsAcs with IG(JPC)=0+(0++). In addition, another two resonances with quantum numbers IG(JPC)=0+(1++) and IG(JPC)=0+(2++) are predicted.
