Measurement of photon production in the very forward direction in deep-inelastic scattering at HERA
Апстракт
The production of photons at very small angles with respect to the proton beam direction is studied in deep-inelastic positron-proton scattering at HERA. 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 LT Q(2) LT 100 GeV2 and inelasticity 0.05 LT y LT 0.6. Cross sections are measured for the most energetic photon with pseudorapidity eta GT 7.9 as a function of its transverse momentum p(T)(lead) and longitudinal momentum fraction of the incoming proton x(L)(lead). In addition, the cross sections are studied as a function of the sum of the longitudinal momentum fraction x(L)(sum) L of all photons in the pseudorapidity range. GT 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 hadron...ic interactions of high energy cosmic rays.
