Hypothesis of quark binding by condensation of gluons in hadrons

TL;DR

This paper proposes a hypothesis that quark binding inside hadrons occurs via gluon condensation, using a renormalization group approach in light-front QCD, leading to a model similar to constituent quark models and AdS/QCD.

Contribution

It introduces a novel hypothesis for quark binding through gluon condensation and formulates it within a renormalization group framework in light-front QCD.

Findings

Gluon condensation hypothesis for quark binding.

Effective constituent dynamics similar to quark models.

Potential for systematic study using RGPEP in QCD.

Abstract

Hypothesis of quark binding through condensation of gluons inside hadrons is formulated in the context of a renormalization group procedure for effective particles (RGPEP) in the light-front (LF) Hamiltonian approach to QCD. At the momentum scales of relative motion of hadronic constituents that are comparable with Lambda_QCD, the hypothetical boost-invariant constituent dynamics is identified using gauge symmetry. The resulting picture of mesons and baryons closely resembles constituent quark models with harmonic oscillator potentials, shares some features of AdS/QCD, and can be systematically studied using RGPEP in QCD.
