Inelasticity distribution and relationship between e+e- and pp hadron-production mechanisms.

Abstract

The inelasticity distribution is used to relate the hadron-production data in [ital e][sup +][ital e[minus]] annihilation to the corresponding data in [ital pp] collisions. If [ital e][sup +][ital e[minus]] annihilation data are used as input, the hadron multiplicity distributions [ital P][sub [ital n]]([ital s]), the average multiplicities [l angle][ital n][prime]([ital s])[r angle], the normalized moments [ital C][sub [ital q]][sup [prime]]([ital s]), the energy dependence of the average transverse momentum [l angle][ital p][sub [ital t]]([ital s])[r angle], the height of the central plateau [ital h]([ital s]), and the strength of the forward-backward multiplicity correlations [ital b]([ital s]) are qualitatively reproduced over the range of energies from those reached at the CERN ISR to [radical][ital s] =900, 1800, and 10[sup 4] GeV in [ital pp] collisions. The discrepancies observed between predicted and experimental values of [ital C][sub [ital q]][sup [prime]]([ital s]), [ital q][ge]4, and [ital h]([ital s])[sub [ital p][ital p]] are indicated and commented upon. Other possible tests of the [ital e][sup +][ital e[minus]-][ital pp] universality are briefly mentioned.
