Jet pseudorapidity distribution in direct photon events in p(p)over-bar collisions at root s=1.8 TeV

Journal article

We present the first measurement of the jet pseudorapidity distribution in direct photon events from a sample of pp̄ collisions at √s= 1.8 TeV, recorded with the Collider Detector at Fermilab. Quantum chromodynamics (QCD) predicts that these events are primarily from hard quark-gluon Compton scattering, qg→qγ, with the final state quark producing the jet of hadrons. The jet pseudorapidity distribution in this model is sensitive to parton momentum fractions between 0.015 and 0.15. We find that the shape of the measured pseudorapidity distribution agrees well with next-to-leading order QCD calculations.
