Aspects of QCD Dynamics from String Theory
Akikazu Hashimoto, Yaron Oz
TL;DR
This paper investigates large N QCD dynamics using supergravity in AdS black hole backgrounds, calculating key physical quantities and comparing them with lattice results, also extending the analysis to QCD_3.
Contribution
It provides a novel supergravity-based approach to compute QCD observables and compares these with lattice data, including new results for QCD_3.
Findings
Mass spectrum consistent with lattice results
Topological susceptibility matches expectations
Gluon condensate values align with previous studies
Abstract
We study dynamical aspects of large N QCD_4 via supergravity on Anti de Sitter black hole geometry. We compute the mass spectrum, the topological susceptibility and the gluon condensate and make a comparison to lattice simulations. We present analogous results for QCD_3.
