Abstract

Production of KS0, Λ, Λ, proton, antiproton, deuteron and antideuteron hadrons has been measured at HERA ep collider using the ZEUS detector. The measurements agree, in general with models and are consistent with measurements made at e+e− colliders, except for an enhancement of baryon production relative to mesons in photoproduction and small yield of antideuterons in comparison to deuterons in Deep Inelastic Scattering (DIS). Bose-Einstein correlations have been demonstrated for charged and neutral kaons. Parameters related to the size and the strength of the kaon source were extracted from the data. They agree with expectations.
