Proton and Antiproton Production In Deep Inelastic Muon-nucleon Scattering At 280 Gev

New results on proton and antiproton production in the target and current fragmentation regions of high energy muon-nucleon scattering are presented. Proton and antiproton production is investigated as a function of Feynmanx and rapidity. No significant difference is observed between production on hydrogen and deuterium targets. Correlations betweenpp,\(p\bar p\) and\(\bar p\bar p\) pairs are analysed and the results are compared with the predictions of the Lund fragmentation model.
