Abstract

Final data measured with the EMC forward spectrometer are presented on the production of forward charged hadrons in μp and μd scattering at incident beam energies between 100 and 280 GeV. The large statistic of 373 000 events allows a study of the semi-inclusive hadron production as a function of z, pT2 and 〈pT2〉 in small Q2, xBj and W bins. Charge multiplicity ratios and differences as a function of z and xBj are given for p, d and n-targets. From the differences of charge multiplicities the ratio of the valence quark distributions of the proton dv(x)/uv(x) is determined for the first time in charged lepton scattering. The Gronau et al. sum rule is tested, the measured sum being 0.31±0.06 s..
