Investigation of potential for heavy tetraquarks with hidden charm

In this paper, we study four-body systems consisting of diquark-antidiquark in the framework of a two-body (pseudo-point) problem. By doing this, the complex structure of the four-body problem becomes more accessible. We solve Lippmann–Schwinger equation numerically and obtain the binding energy of charm tetraquarks. Then we obtain the stability interval of a few suitable potentials for heavy tetraquarks with hidden charm. The obtained results offer the most appropriate of these potentials for charm tetraquarks.
