Abstract

Using data from the Fermilab fixed target experiment E665, general properties of forward produced charged hadrons in μp interactions at a primary muon energy of 470 GeV are investigated. The normalized inclusive single-particle distributions for Feynman-x D(x_F) and for the transverse momentum D(p_t², x_F) are measured as a function of W and Q². The dependence of the average transverse momentum squared 〈p_t²〉 on x_F, W and Q² is studied. The increasing contribution from diffractive production as Q² decreases leads to a reduction of the average charged hadron multiplicities at low (positive) x_F and an enhancement at large x_F, for Q² ≲ 10 GeV². It also reduces 〈p_t²〉 for Q² ≲ 5 GeV² and 0.4 ≲ x_F < 1.0.
