Can QCD be tested in high-energy low-p/sub perpendicular to / hadronic physics?

It is suggested that the broadening of the p/sub perpendicular to / distribution which is predicted by QCD and which has been seen in e ^{+}e^{-} at highest PETRA energies should be reached in low-p /sub perpendicular to / proton-proton collisions (using the technique of removal of the leading-particle effect) at c.m. energies \sqrt{s}>or=400 GeV. The preliminary data from the pp Cern collider support this estimate, which agrees with cosmic-ray analysis.
