Abstract

New data are presented on charged particle pseudorapidity distributions for inelastic events produced at c.m. energies {Mathematical expression}=200 and 900 GeV. The data were obtained at the CERN antiproton-proton Collider operated in a new pulsed mode. The rise of the central density ρ(0) at energies up to {Mathematical expression}=900 GeV has been studied. A new form of central region scaling is found involving the density ρ_n(0) for charged multiplicity n, namely that the scaled central density ρ_n(0)/ρ(0) expressed as a function of z=n/〈n〉 is independent of s. Scaling in the fragmentation region holds to 10-20%, and the small amount of scalebreaking observed here could be accommodated within the framework suggested by Wdowcyk and Wolfendale to account for both accelerator and cosmic ray data.
