Abstract

We have determined the double inclusive cross-section for opposite-side high-p_T photons and away-side jets with θ_γ≈θ_jet≈90° produced in pp collisions at the CERN Intersecting Storage Rings at {Mathematical expression} GeV. Under the assumption that these events arise predominantly from the QCD gluon Compton process we have calculated the gluon structure function in the range 0.15≦x≦0.30 at an average square of the four-momentum transfer of 40 GeV²/c². The data favour a soft gluon distribution in the proton.
