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.
