Effect of Confinement of Gluons and One Pion Exchange in Nucleon-Nucleon Interaction

TL;DR

This paper investigates how confinement of gluons and one pion exchange influence nucleon-nucleon interactions using a relativistic harmonic model and the Resonating Group Method.

Contribution

It introduces a detailed analysis of gluon and pion exchange effects within a relativistic framework for nucleon interactions.

Findings

Confined one gluon exchange significantly affects the interaction potential.

One pion exchange contributes notably to the nucleon-nucleon interaction.

The combined effects modify the potential landscape in the studied channels.

Abstract

The Nucleon-Nucleon interaction in the singlet ($^1 S_0$) and triplet ($^3 S_1$) channels have been studied in the framework of Relativistic Harmonic Model using the Resonating Group Method in Born-Oppenheimer approximation. The full Hamiltonian consists of the kinetic energy, two body confinement potential, confined one gluon exchange potential and one pion exchange potential. Contribution of Confined One Gluon Exchange Potential and One Pion Exchange Potential to the adiabatic nucleon-nucleon interaction potential is discussed.
