Perturbative Confinement

TL;DR

This paper proposes a perturbative approach to confinement in quantum chromodynamics by introducing a counter term to handle infrared divergences, enabling calculations of hadron properties and the string tension.

Contribution

It introduces a novel perturbative method with a counter term to address confinement and compute the string constant in QCD.

Findings

Perturbative expansion can approximate hadron properties.

Derived an expression for the string constant in terms of QCD parameters.

Method potentially bridges perturbative techniques with confinement phenomena.

Abstract

A Procedure is outlined that may be used as a starting point for a perturbative treatment of theories with permanent confinement. By using a counter term in the Lagrangian that renormalizes the infrared divergence in the Coulomb potential, it is achieved that the perturbation expansion at a finite value of the strong coupling constant may yield reasonably accurate properties of hadrons, and an expression for the string constant as a function of the QCD Lambda parameter.
