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 $$ep$$epscattering at HERA are presented as a function of the Feynman variable $$x_F$$xFand of the centre-of-mass energy of the virtual photon-proton system $$W$$W. The data are taken with the H1 detector in the years 2006 and 2007 and correspond to an integrated luminosity of $$131~\text {pb}^{-1}$$131pb-1. The measurement is restricted to photons and neutrons in the pseudorapidity range $$\eta >7.9$$η>7.9and covers the range of negative four momentum transfer squared at the positron vertex $$6<Q^2<100$$6<Q2<100 GeV$$^2$$2, of inelasticity $$0.05<y<0.6$$0.05<y<0.6and of $$70<W<245~$$70<W<245GeV. To test the Feynman scaling hypothesis the $$W$$Wdependence of the $$x_F$$xFdependent 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.
