Two-particle distributions ine+e−jets

Abstract

We apply the "jet calculus" of Konishi, Ukawa, and Veneziano (KUV) to the two-particle spectra of $e^{+}{e}^{-}$ jets. This computation uses single-particle fragmentation functions and the KUV analysis of leading logarithms to predict the multiparticle spectra entirely from the single-particle data. The effects of charm and heavier flavors are discussed and a simple prescription for inverting the necessary double moments is given. The double-differential cross section $\frac{d\sigma }{d{x}_{1}d{x}_2}$ is displayed for various combinations of mesons and the antiproton.
