Unitarity, asymptotic constraints and hadronic slopes

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

The connection between multiparticle unitarity and the structure of hadronic slopes is investigated within a simple model for the nondiffractive production amplitudes in which the (energy dependent) normalization in the popular form of the negative binomial distribution is taken as input. It is shown that the model can be made consistent with all known high energy constraints following from asymptotic theorems and experimental information in the sense that simple parametrizations of the (three) energy dependent parameters of the model satisfying all these constraints allow us to account for all thepp and\(\bar pp\) slope data from “low” to the highest available energies.
