every hadron. We could then put our hypothesis to the test, and compared the results to e $^{+}$e − collisions made at LEP and PEP-PETRA. The results were surprisingly good. It is also interesting to note that although we included a strangeness supression factor, γ$_{s}$ , in the manner of [3], we found it to be almost equal to one in both fits. This suggests that in practice such a parameter is not necessary in our model. In addition, our holographic model of QCD predicts over-massive excited states, and this probably leads to a suppression of the pion yields in table 8.2. A holographic model with a more accurate hadronic mass spectrum would almost certainly give better results. The model of hadronization presented here is applicable to all particle- antiparticle annihilation events, where the fireball after the collision has no residual quantum numbers. Broadening this model to include events such as deep inelastic proton-proton scattering, and heavy ion collisions would clearly be desirable. We leave such an analysis for the future. 119
