Strangeness Production at low Q2 in Deep-Inelastic ep Scattering at HERA
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 < Q2 < 100 GeV2 and the inelasticity 0.1 < y < 0.6. The Ks and Lambda production cross sections and their ratios are determined. Ks production is compared to the production of charged particles in the same region of phase space. The Lambda - anti-Lambda asymmetry is also measured and found to be consistent with zero. Predictions of leading order Monte Carlo programs are compared to the data.
