Tetraquarks as Diquark Antidiquark Bound Systems

TL;DR

This paper investigates heavy tetraquarks as diquark-antidiquark bound states, solving the Lippman-Schwinger equation numerically to predict their masses and binding energies, aligning well with existing data.

Contribution

It introduces a novel approach by modeling tetraquarks as diquark-antidiquark systems and solving a two-body problem to compute their properties.

Findings

Calculated masses and binding energies of charm tetraquarks.

Results agree with theoretical predictions and experimental observations.

Validated the diquark-antidiquark model for heavy tetraquarks.

Abstract

In this paper, we study four-body systems consisting of diquark antidiquark, and we analyze diquark-antidiquark in the framework of a two body (pseudo point) problem. We solve Lippman Schwinger equation numerically for charm diquark antidiquark systems and find the eigenvalues to calculate the binding energies and masses of heavy tetraquarks with hidden charms. Our results are in good agreement with theoretical and experimental data.
