THE INCLUSIVE TRANSVERSE-MOMENTUM DISTRIBUTION IN HADRONIC SYSTEMS PRODUCED IN PROTON-PROTON COLLISIONS

Summary. The single.particle inclusive transverse-momentum distribution in the multiparticle systems produced in low-1~T proton-proton interactions at ~- 30 and 62 GoV has been studied. The analysis was performed removing from the final state the leading proton and redefining the effective hadronie energy available for particle production. Excellent agreement for effective hadronic energies up to 13 GoV is found between (pp) and (e+e-). At higher energy the (pp) data show a less pronounced growth than the (e+e -) data.
