Charge prong multiplicity distributions in proton-proton collisions at 28.5 Ge V/c

Abstract

Using the Multiparticle Argo Spectrometer System, we have measured the charge prong multiplicity distribution as a function of the kinematic variable of the fast recoil proton for 190,000 events in the reaction pp→p+ANYTHING at 28.5 GeV/c. We find the distributions to be similar to charge prong multiplicities for pp →ANYTHING at different energies. We have looked for a KNO type scaling in W, P and t and find strong evidence only for scaling over W for a fixed range of t. Finally, the scaled distributions, both total and associated, as a function of Ware presented for comparison.
