D0-Branes As Light-Front Confined Quarks

TL;DR

This paper explores how D0-brane matrix quantum mechanics can model various aspects of confined phase Light-Front QCD, including inter-quark potentials, hadron properties, and scattering, linking string theory concepts with strong interaction physics.

Contribution

It demonstrates that D0-brane matrix quantum mechanics derived from pure Yang-Mills theory can replicate key features of confined QCD, offering a novel theoretical approach.

Findings

Reproduces phenomenological inter-quark potentials

Explains the whiteness of hadrons

Analyzes scattering amplitudes in the D0-brane framework

Abstract

We argue that different aspects of Light-Front QCD at confined phase can be recovered by the Matrix Quantum Mechanics of D0-branes. The concerning Matrix Quantum Mechanics is obtained from dimensional reduction of pure Yang-Mills theory to 0+1 dimension. The aspects of QCD dynamics which are studied in correspondence with D0-branes are: 1) phenomenological inter-quark potentials, 2) whiteness of hadrons and 3) scattering amplitudes. In addition, some other issues such as the large-N behavior, the gravity--gauge theory relation and also a possible justification for involving ``non-commutative coordinates'' in a study of QCD bound-states are discussed.
