Abstract

We have used the energy-energy angular pattern of hadrons in inelastic muon-deuteron scattering to study perturbative QCD effects and to extract the gluon distribution function ηG(η) of the nucleon, where η is the fractional momentum carried by the gluon. The data were taken with the E665 spectrometer using the Fermilab Tevatron muon beam with a mean beam energy of 490 GeV. We present ηG(η) for 0.005 < η < 0.05 and at an average Q2 of 8 GeV2 using this new technique. We find that ηG(η) in this region can be described by ηG(η) ∝ ηλ with λ = -0.87±0.09(stat.)±0.370.32(sys.). We compare our results to expectations from various parametrizations of the parton distribution function and also to results from HERA.
