Title: Measurement of the nuclear multiplicity ratio or image hadronization K0s at CLAS

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 K0s 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 K0sand the transverse momentum squared p2T of the K0s. We find that the multiplicity ratios for K0s are reduced in the nuclear medium at high z and low p2T, with a trend for the K0s transverse momentum to be broadened in the nucleus for large p2T.
