Résumé :
48 years ago, the Veneziano amplitude was formulated to model the 2->2 scattering of mesons, the analysis of which was a cornerstone for the formulation of early string theory. Now, modern string theory is concerned with the holographic duality, involving highly curved spaces in which Veneziano’s result is not easily seen, but which in theory should give a better approximation to the realistic meson scattering amplitude, one that includes physics of confinement and asymptotic freedom. We derive a set-up that can, in certain limits, produce a correction to the standard Veneziano result, coming from the curvature of the holographic duals involved, that aims to implement these improvements systematically, and discuss the consistency of the result.
