Strangeness Production at low Q^2 in Deep-Inelastic ep Scattering at HERA

Understand

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_s and Lambda production cross sections and their ratios are determined.
• K_s production is compared to the production of charged particles in the same region of phase space.
