Inclusive Prompt Photon Production in Deep Inelastic Scattering at H1

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 $3 < E_T^γ< 10 GeV$ and for the pseudorapidity range of the photons $-1.2 < η^γ< 1.8$. They are measured differentially as a function of $E_T^γ$ and $η^γ$. The results are compared with the predictions of a leading order calculation, which is in reasonable agreement with the inclusive measurement.
