Title
Measurement of Feynman-x spectra of photons and neutrons in the very forward direction in deep-inelastic scattering at HERA
Author
Abstract
Measurements of normalised cross sections for the production of photons and neutrons at very small angles with respect to the proton beam direction in deep-inelastic ep scattering at HERA are presented as a function of the Feynman variable x(F) and of the centre-of-mass energy of the virtual photon-proton system W. The data are taken with the H1 detector in the years 2006 and 2007 and correspond to an integrated luminosity of 131 pb(-1). The measurement is restricted to photons and neutrons in the pseudorapidity range eta > 7.9 and covers the range of negative four momentum transfer squared at the positron vertex 6 < Q(2) < 100 GeV2, of inelasticity 0.05 < y < 0.6 and of 70 < W < 245 GeV. To test the Feynman scaling hypothesis the W dependence of the xF dependent cross sections is investigated. Predictions of deep-inelastic scattering models and of models for hadronic interactions of high energy cosmic rays are compared to the measured cross sections.
