How Well Does AdS/QCD Describe QCD?
Joshua Erlich (College of William, Mary)
TL;DR
This paper investigates why AdS/QCD models, inspired by string theory, effectively describe low-energy QCD phenomena despite their simplified assumptions, and addresses criticisms of these models.
Contribution
It provides an analysis of the success of AdS/QCD models in capturing hadronic physics and responds to critiques, clarifying their applicability and limitations.
Findings
AdS/QCD models outperform expectations at energies below a few GeV.
The paper offers explanations for the models' surprising accuracy.
It addresses and counters common criticisms of AdS/QCD approaches.
Abstract
AdS/QCD is an extra-dimensional approach to modeling hadronic physics, motivated by the AdS/CFT correspondence in string theory. AdS/QCD models are often more accurate than would have been expected at energies below a few GeV. We address the question of why these models are so successful, and respond to some of the criticisms that have been waged against these models.
