Book excerpt: "This thesis presents a first study of various aspects of $K sp0$ and $ Lambda$ production in neutral current deep inelastic scattering of 27.5 GeV positrons and 820 GeV protons. The data were accumulated with the ZEUS detector at HERA in the 1994 run period. The average multiplicities for the neutral strange particle production as functions of pseudorapidity $ eta$ and transverse momentum $p sb{t}$ have been determined in the kinematic range 10 $GeV sp20.04.$ The particle and energy flow with respect to the struck quark direction, as well as the dependence of the average production rate as function of the four-momentum transfer $Q sp2$ and the hadronic centre of mass energy W of the ep scattering process have been studied. The K$ sp0$ and $ Lambda$ multiplicities in the kinematic range 10 $GeV sp20.04$ are compared with the results from data from the 1993 run period with 26.7 GeV electrons and 820 GeV protons. The production mechanisms of $K sp0$ in events with and without large rapidity gaps with respect to the proton direction are compared in order to probe differences in diffractive and non-diffractive scattering processes." --
