Description
Measurements of the normalised cross sections for the production of
photons and neutrons at very small angles with respect to the proton
beam direction in deep-inelastic positron proton scattering at HERA
are presented as a function of the variable Feynman-x. 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 < Q$^2$ < 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 the cross sections on W is
investigated. Predictions of models of deep inelastic scattering and
models of the hadronic interactions of high energy cosmic rays are
compared to the measured cross sections.
