Study of Tetraquarks with a simple model

TL;DR

This paper investigates tetraquarks using a simplified model that reduces internal degrees of freedom, employing finite differences and scattering theory to identify bound states and resonances, and calculating their masses and widths.

Contribution

Introduces a simplified approximation method for studying tetraquarks, focusing on bound states and resonances, with calculations of their properties.

Findings

Existence of bound states and resonances in tetraquarks

Calculated masses and widths of resonances

Validated the simplified model's effectiveness

Abstract

Tetraquarks are studied with an approximation which reduces the in- ternal degrees of freedom of the system, using both finite differences and scattering theory. The existence of bound states and resonances is inspected and the masses and widths of the found resonances are calculated.
