Hadronization at the AdS wall

TL;DR

This paper models hadronization using AdS/CFT, demonstrating string dynamics, oscillations, breaking, and rho meson production in a QCD-like setting within a back-reacted geometry.

Contribution

It introduces a novel holographic model of hadronization with explicit string breaking and meson production in a back-reacted AdS geometry.

Findings

Strings develop linear QCD-like behavior

String breaking induces rho meson production

Explicit computation of rho meson production at string endpoints

Abstract

We describe hadronization events, using the AdS/CFT Correspondence, which display many of the qualitative features expected in QCD. In particular we study the motion of strings with separating end points in a back-reacted hard wall geometry. The solutions show the development of a linear QCD-like string. The end points oscillate in the absence of string breaking. We introduce string breaking by hand and evolve the new state forward in time to observe the separation of two string segments. A kink associated with this breaking evolves to the end points of the string inducing rho meson production. We explicitly compute the rho meson production at the end point.
