Inclusive charged particle cross sections in photoproduction at HERA

Academic Article


  • Cross sections are presented for the inclusive production of charged particles measured in electron-proton collisions at low Q2 with the H1 detector at HERA. The transverse momentum distribution extends up to 8 GeV/c. Its shape is found to be harder than that observed in pp collisions at comparable centre-of-mass energies √Sγp ≈ √Spp ≈ 200GeV, and also harder than in γp collisions at lower energies √Sγp ≈ 18 GeV. Results from quantum chromodynamics (QCD) calculations agree with the measured transverse momentum and pseudorapidity cross sections. © 1994.
