摘要：

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 ppBAR collisions at comparable centre-of-mass energies square-root s(gammap) almost-equal-to square-root s(ppBAR) almost-equal-to 200 GeV, and also harder than in gammap collisions at lower energies square-root s(gammap) almost-equal-to 18 GeV. Results from quantum chromodynamics (QCD) calculations agree with the measured transverse momentum and pseudorapidity cross sections.
