The influence of the nuclear medium on lepto-production of hadrons was studied in the HERMES experiment at DESY in semi-inclusive deep-inelastic scattering of 27.6 GeV and 12 GeV positrons off deuterium, and off light and heavy targets. The differential multiplicity for nuclei relative to that of deuterium has been measured for the first time for 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 the hadron transverse momentum squared pt2.
