Evidence for a New Scaling Hypothesis in High-Energy Collisions

Abstract

Single-particle distributions in transverse and longitudinal momenta have been studied in $\mathrm{pp}$ interactions at 300 GeV/c. By comparing these distributions for different multiplicities of produced particles and with published low-energy data, we put forth the hypothesis of a new type of scaling: The shape of distributions in ${p}_{T}$ and ${p}_{L}$ are independent of multiplicity and incident energy.
