Description

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 anti pp collisions at comparable centre-of-mass energies √sγp∼√s anti pp∼200 GeV, 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. (orig.)
