摘要：

Using data from the Fermilab fixed target experiment E665, general properties of forward produced charged hadrons in mu p interactions at a primary muon energy of 470 GeV are investigated. The normalized inclusive single-particle distributions for Feynman-x D(chi(F)) and for the transverse momentum D(p(t)(2),chi(F)) are measured as a function of W and Q(2). The dependence of the average transverse momentum squared (p(t)(2)) on chi(F), W and Q(2) is studied. The increasing contribution from diffractive production as Q(2) decreases leads to a reduction of the average charged hadron multiplicities at low (positive) chi(F) and an enhancement at large chi(F), for Q(2) less than or similar to 10 GeV2. It also reduces (p(t)(2)) for Q(2) less than or similar to 5 GeV2 and 0.4 less than or similar to chi(F) < 1.0.
