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

abstract

  • We present the first measurement of the jet pseudorapidity distribution in direct photon events from a sample of (Formula presented) collisions at (Formula presented) recorded with the Collider Detector at Fermilab. Quantum chromodynamics (QCD) predicts that these events are primarily from hard quark-gluon Compton scattering, (Formula presented) 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. 1998 The American Physical Society.
