Energetic hadron jets at TeV energies
We use recently measured proton gluon distributions to revise previous QCD perturbation-theory calculations of very-large-p/sub perpendicular/ ..pi../sup 0/ and jet inclusive predictions. The CERN ISR large-p/sub perpendicular/ ..pi../sup 0/ inclusive cross sections and new hard-jet inclusive cross sections from the CERN p-barp collider are well described with a common cutoff ..lambda.. and no other adjustable parameters, using the one-loop coupling parameter ..cap alpha..(Q/sup 2/). Predictions are made for large-p/sub perpendicular/ ..pi../sup 0/ production at the Fermilab collider, Tevatron I, and a hypothetical future collider of c.m. energy 10 or 20 TeV. As the energy increases, the gluon-gluon collisions are predicted to become more and more significant, exceeding 60% at 20-TeV energies for p/sub perpendicular/ up to 500 GeV/c.
