| Abstract |
Results are presented on the inclusive production of isolated prompt
photons in deep inelastic scattering with a four-momentum transfer of
Q^2>4 GeV^2. The cross sections are measured for the transverse momentum
range of the photons 3 < E_T^gamma < 10 GeV and for the pseudorapidity
range of the photons -1.2 < eta^gamma < 1.8. They are measured differentially
as a function of E_T^gamma and eta^gamma.
The results are compared with the predictions of a new leading
order calculation, which is in reasonable agreement with the inclusive
measurement. Comparisons with the predictions of the event generator
PYTHIA are also presented. |
