Contribution

It introduces a method to compute holographic corrections to meson scattering amplitudes in confining backgrounds, illustrating the process with two explicit examples.

Findings

Holographic corrections qualitatively modify meson scattering amplitudes.

The corrections are applicable to both four-point and higher-point functions.

The approach is generalizable across various confining string backgrounds.

Abstract

We compute meson scattering amplitudes using the holographic duality between confining gauge theories and string theory, in order to consider holographic corrections to the Veneziano amplitude and associated higher-point functions. The generic nature of such computations is explained, thanks to the well-understood nature of confining string backgrounds, and two different examples of the calculation in given backgrounds are used to illustrate the details. The effect we discover, whilst only qualitative, is re-obtainable in many such examples, in four-point but also higher point amplitudes.
