Measurements of Production Properties of K0S mesons and Lambda hyperons in Proton-Carbon Interactions at 31 GeV/c

Understand

Spectra of K0S mesons and Lambda hyperons were measured in p+C interactions at 31 GeV/c with the large acceptance NA61/SHINE spectrometer at the CERN SPS.

• The data were collected with an isotropic graphite target with a thickness of 4% of a nuclear interaction length.
• Interaction cross sections, charged pion spectra, and charged kaon spectra were previously measured using the same data set.
• Results on K0S and Lambda production in p+C interactions serve as reference for the understanding of the enhancement of strangeness production in nucleus-nucleus collisions.
