Description

Measurements of very forward neutron and photon production as a function of Feynman-x in deep-inelastic ep scattering at HERA are presented. The data are taken with the H1 detector in the years 2006 and 2007 and correspond to an integrated luminosity of 126 pb^-1. The analysis covers the range of negative four momentum transfer squared at the positron vertex 6<Q2<100 GeV^2, inelasticity 0.05<y<0.6 and the centre-of-mass energy of the virtual photon-proton system 70<W<245 GeV. The dependence of cross sections on W is investigated. The cross sections are compared to the predictions of DIS models and models of the hadronic interactions of high energy cosmic rays.
