High-Energy Pion Scattering in Holographic QCD: A Comparison with Experimental Data

Abstract

Following Polchinski and Strassler [1] and our previous work [2], we study high-energy pion scattering in the holographic QCD hard-wall model. In particular, we focus on comparing our predictions for the angular dependence of ${\pi }^{+}{\pi }^{-}\to {\pi }^{+}{\pi }^{-}$ scattering with experimental data extracted from the process ${\pi }^{-}p\to {\pi }^{+}{\pi }^{-}n$. Having previously shown that our approach reproduces the constituent counting rule found in QCD, we now observe qualitative agreement between our predictions and the extracted data in the high-energy fixed-angle regime. We also provide predictions for all other 2-to-2 pion scattering processes. Our approach can be extended to a broader range of meson and glueball scattering processes in various holographic QCD models.
