Energy-Momentum Distribution ine+e−Annihilation

Abstract

Analytic formulas are derived for the energy, longitudinal-, and transverse-momentum distributions of "soft" radiation for $e^{+}{e}^{-}\to q\overline{q}$+ gluons in a Bloch-Nordsieck approach to quantum chromodynamics. A comparison with the data of Hanson et al. obtained at SPEAR is made for the resulting hadronic longitudinal- and transverse-momentum distribution.
