Study of the ground state energies of some nuclei using hybrid model

TL;DR

This paper investigates the ground state energies of light nuclei using a hybrid model that combines quark-quark and nucleon-nucleon interactions within a semi-relativistic framework, highlighting small but notable effects.

Contribution

It introduces a hybrid model combining QQ and NN interactions with OBEP and CDP potentials to calculate nuclear ground-state energies.

Findings

Quark-quark interactions slightly affect ground state energies.

The model predicts energies with small perturbations (~6.7 and 1.2 units).

Hybrid approach is suitable for light nuclei analysis.

Abstract

The quark-quark QQ interaction as a perturbed term to the nucleon-nucleon interaction NN without any coupling between them is studied in a hybrid model. This model is used to calculate the ground-state energies of 2H1 and 4He2 nuclei. In a semi-relativistic framework, this model is encouraged for light nuclei and the instanton induced interaction by using the QQ potential and the NN interaction for a small scale around the hadron boundaries. This hybrid model depends on two theories, the one-boson exchange potential OBEP and the Cornell-dressed potential CDP for QQ. A small effect of quark-quark interaction is obtained on the values of the ground state energies, around 6.7 for 2H1 and 1.2 for 4He2 by using the considered hybrid model.
