Multiparticle production in lepton-nucleus collisions and relativistic string models
Nuclear attenuation of the leading (xf>0) hadron and the nuclear enhancement of target fragmentation (xf<0) hadrons in lepton-nucleus reactions are calculated via a (3+1)-dimensional string-parton model. A (1+1)-dimensional string model is used to investigate the dependence of rapidity distributions on the lepton energy loss, =10100 GeV, the atomic number, A=1200, the effective string tension, =0.52 GeV/fm, the string decay constant, 0=0.52 fm/c, and the string flip cross section, lq=030 mb. The (3+1)-dimensional string-parton model includes inelastic final state cascading of produced hadrons in the nucleus. We show how the A dependence of hadronic production in lepton-nucleus collisions, especially in the xf<0 region, may be used to extract information on quark propagation and hadronization in nuclei. © 1992 The American Physical Society.
