A recombination model for large-PT reactions

A difficult theoretical problem in large P_T reactions is to reproduce simultaneously the observed single-particle distributions and the distribution of 〈P_out〉² versus X²_E for different values of $\text{s}$ and P^trig_T. The purpose of this letter is to report successful fits to these distribution in a “recombination” model and to present the predictions of the model at $\text{s}\text{=540}\text{GeV}$, corresponding to the CERN PP? collider.
