On high-energy multiparticle production and elastic-scattering processes

Abstract

For many-particle production we study a model which assumes at fixed impact parameter a statistical picture of fireball formation and decay. We obtain in this way on the one hand for the usual statistical model an extension which includes angular-momentum conservation and allows predictions for all inelastic and corresponding absorptive elastic cross-sections, on the other a «central collision» counterpart of the peripheral model. The asymptotic predictions for production processes are discussed and compared to those of the usual statistical model and of the multiperipheral model. The resulting form for elastic and total cross-sections, obtained by unitarity, agrees with that given by Van Hove's uncorrelated particle model.
