Measurement of photon production in the very forward direction in deep-inelastic scattering at HERA

Popis výsledku v původním jazyce

The production of photons at very small angles with respect to the proton beam direction is studied in deep-inelastic scattering at HERA. The data are taken with the H1 detector in the years 2006-07 and correspond to an integrated luminosity of 126pb1. The analysis covers the range of negative four momentum transfer squared at the positron vertex 67.9 as a function of its transverse momentum pleadT and longitudinal momentum fraction of the incoming proton xleadL. In addition, the cross sections are studied as a function of the sum of the longitudinal momentum fraction xsumL of all photons in the pseudorapidity range ?>7.9. The cross sections are normalised to the inclusive deep-inelastic scattering cross section and compared to the predictions of models of deep-inelastic scattering and models of the hadronic interactions of high energy cosmic rays.
