Abstract
The production of neutral strange hadrons is investigated using deep-inelastic scattering events measured with the H1 detector at HERA. The measurements are made in the phase space defined by the negative four-momentum transfer squared of the photon 2<Q 2<100 GeV 2 and the inelasticity 0.1<y<0.6. The K s0 and Λ(Λ̄) production cross sections and their ratios are determined. K s0 production is compared to the production of charged particles in the same region of phase space. The Λ- Λ̄ asymmetry is also measured and found to be consistent with zero. Predictions of leading order Monte Carlo programs are compared to the data. © 2009 Springer-Verlag / Società Italiana di Fisica.
