K_s⁰ and Λ Production in DIS at HERA — •Amita Raval — DESY, Notkestrasse 85, 22607 Hamburg

The production of inclusive K_s mesons and Λ baryons in deep inelastic positron-proton scattering (DIS) has been studied with the ZEUS detector using an integrated luminosity of 60 pb⁻¹. The cross sections presented here are in the kinematic range of 20 < Q² < 500 GeV². Also presented here is a measurement of K_sK_s final state in electron-proton DIS for the complete HERA I data set corresponding to an integrated luminosity of 120 pb⁻¹. The observation of f₂’(1525) and f_J(1710) mesons is reported.
