A holographic model of hadronization

Abstract

We study hadronization of the final state in a particle-antiparticle annihilation using a holographic gravity dual description of QCD. At the point of hadronization we match the events to a simple (Gaussian) energy distribution in the five dimensional theory. The final state multiplicities are then modelled by calculating the overlap between the Gaussian and a set of functions in the fifth dimension which represent each hadron. We compare our results to those measured in e+e- collisions at LEP and PEP-PETRA. Hadron production numbers, which differ in range by four orders of magnitude, are reproduced to well within a factor of two.
