Color Transparency and Light Front Holographic QCD

TL;DR

This paper investigates color transparency within the framework of light front holographic QCD, revealing that current formulations lack the small-sized configurations necessary for this phenomenon, challenging existing assumptions in high-energy nuclear physics.

Contribution

It demonstrates that light front holographic QCD wave functions do not include point-like configurations, questioning its applicability to color transparency phenomena.

Findings

Light front holographic QCD wave functions lack PLCs.

Color transparency predictions require PLCs, absent in current models.

Challenges the use of holographic QCD for high-momentum transfer processes.

Abstract

Color transparency, the reduction of initial- or final-state interactions in coherent nuclear processes, is a natural prediction of QCD provided that small-sized or point-like configurations (PLCs) are responsible for high-momentum transfer, high-energy, semi-exclusive processes. I use the FMS criteria for the existence of PLCs to show that the wave functions of light front holographic QCD, as currently formulated, do not contain a PLC.
