The influence of cold nuclear matter on lepto-production of hadrons in semi-inclusive deep inelastic scattering is measured using the CLAS detector in Hall B at Jefferson Lab and a 5.014 GeV electron beam. We report the K-s(0) multiplicity ratios for targets of C, Fe, and Pb relative to deuterium as a function of the fractional virtual photon energy z transferred to the K-s(0) and the transverse momentum squared p(T)(2). of the K-s(0). We find that the multiplicity ratios for K-s(0) are reduced in the nuclear medium at high z and low p(T)(2), with a trend for the K-s(0) momentum to be broadened in the nucleus for large p(T)(2).
