Abstract New data are presented on charged particle pseudorapidity distributions for inelastic events produced at c.m. energies $$\sqrt s $$ =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 $$\sqrt s $$ =900 GeV has been studied. A new form of central region scaling is found involving the densityρ n (0) for charged multiplicityn, namely that the scaled central densityρ n (0)/ρ(0) expressed as a function ofz=n/〈n〉 is independent ofs. 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.
