Diquarkyonic matter: quarks, diquarks and baryons

TL;DR

This paper explores the color-spin interactions in multiquark systems, demonstrating that multiquark configurations align with diquarkyonic matter characteristics, especially when surrounded by three or more baryons.

Contribution

It extends previous models by analyzing multiquark states with up to five surrounding baryons and all possible diquark probes in flavor SU(2) and SU(3) symmetries.

Findings

A quark becomes more stable than a baryon with three or more surrounding baryons.

The three-body confinement potential does not influence the results.

Color-spin interactions support the diquarkyonic matter configuration.

Abstract

In this work, we investigate the color-spin interaction of a quark, a diquark and a baryon with their surrounding baryons and/or quark matter. We extend our previous work by increasing the maximum number of surrounding baryons to 5 and additionally consider all possible diquark probes that are immersed in such surroundings. This is accomplished by classifying all possible flavor and spin states of the resulting multiquark configuration in both the flavor SU(2) and SU(3) symmetric cases. We also discuss the three-body confinement potential and show that this does not contribute to the outcome. Furthermore, we find that a quark becomes more stable than a baryon when the number of surrounding baryons is three or more. Finally, when we consider the internal color-spin factor of a probe, our results show that the effects of the color-spin interaction of a multiquark configuration is consistent with the so-called diquarkyonic configuration.
