Holographic Corrections to the Veneziano Amplitude

TL;DR

This paper presents a holographic approach to compute meson scattering amplitudes in a QCD-like theory, recovering the Veneziano amplitude and analyzing curvature-induced corrections that reflect QCD's UV behavior.

Contribution

It introduces a holographic method to calculate corrections to the Veneziano amplitude in a curved string background dual to QCD-like theories.

Findings

Recovered the Veneziano amplitude holographically.

Computed perturbative corrections due to background curvature.

Found deviations from linear Regge trajectories consistent with QCD UV properties.

Abstract

We propose a holographic computation of the $2\rightarrow 2$ meson scattering in a curved string background, dual to a QCD-like theory. We recover the Veneziano amplitude and compute a perturbative correction due to the background curvature. The result implies a small deviation from a linear trajectory, which is a requirement of the UV regime of QCD.
