【 摘 要 】

The influence of the nuclear medium on lepto-production of hadrons was studied in theHERMES experiment at DESY in semi-inclusive deep-inelastic scattering of 27.6 GeV and 12GeV positrons off deuterium, and off light and heavy targets. The differentialmultiplicity for nuclei relative to that of deuterium has been measured for the first timefor various identified hadrons (p⁺,p^-,p⁰,K⁺,K^-,p and p as a function of the virtual photon energy n, the fraction z of this energy transferred to the hadron, and thehadron transverse momentum squared p_t².
