Measurement of the nuclear multiplicity ratio for K0 s hadronization 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 Kos 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 Kos and the transverse momentum squared P2T of the Kos. We find that the multiplicity ratios for Kos are reduced in the nuclear medium at high z and low P2T, with a trend for the Kos transverse momentum to be broadened in the nucleus for large P2T.
