Benchmark cross sections forp bar p collisions at 1.8 TeV

High-energyp (bar p) collisions provide many quantitative tests of the standard model. Of particular interest are “hard scattering” processes, which test not only standard model matrix elements and higher order perturbative corrections, but also the distributions of quarks and gluons in the colliding hadrons. We present detailed comparisons of data from the CERNSp (bar p) S collider with theory, incorporating up-to-date parton distributions derived from recent deep inelastic scattering data. Encouraged by the excellent agreement between data and theory at (sqrt s ) =630GeV, we present a complete set of “benchmark” predictions for the FNALp (bar p) collider at (sqrt s ) =1.8TeV.
