摘要：
A nonrelativistic model is used to study hidden-charm tetraquarks within a diquark-antidiquark configuration. Using the perturbation theory, we estimate the masses of the heavy tetraquarks with hidden charm. Our present analysis suggests the charmonium-like states: X(3860), X(3872), Zc(3943), X(4140), Zc(4430) and X(4700) can be accommodated in tetraquark picture. We particularly find that the Zc(4430) may be treated as the first radial excitation of X(3872).
