Abstract
- A measurement of the gluon structure fusion using direct photon events observed with the UA2 detector in p p collisions at √ s =630 GeV is presented. The x -range covered by this analysis is between 0.049 and 0.207 and the Q 2 range is between 280 GeV 2 and 3670 GeV 2 . The data sample corresponds to an integrated luminosity of 7.14 pb −1 . The results are found to be in good agreement with the gluon distributions measured in deep inelastic scattering experiments extrapolated to the UA2 Q 2 values.
