New scaling of charged particle pseudorapidity distributions at collider energies

A new scaling form is proposed for charged particle pseudorapidity (η) distributions on the basis of scaling in the mean hypothesis. Our new scaling accounts well the recent UA5 data of η distributions in various intervals of charged multiplicity for non single-diffractive events at energies \(\sqrt s = 200\) and 900 GeV. Similar scaling of inclusive η distributions is theoretically derived, and the validity of this scaling is assured in comparison with the data of ISR and collider energies.
