Abstract
This paper presents measurements of K0 and Λ production in neutral current, deep inelastic scattering of 26.7 GeV electrons and 820 GeV protons in the kinematic range 100.04. Average multiplicities for K0 and Λ production are determined for transverse momenta pT>0.5 GeV and pseudorapidities |η|<1.3. The multiplicities favour a stronger strange to light quark suppression in the fragmentation chain than found in e+e- experiments. The production properties of K0' s in events with and without a large rapidity gap with respect to the proton direction are compared. The ratio of neutral K0' s to charged particles per event in the measured kinematic range is, within the present statistics, the same in both samples. © 1995 Springer-Verlag.
