K⁰(K⁰) Production in Two-Photon Processes at TRISTAN

الأصل · EN

We have carried out an inclusive measurement of K⁰(K⁰) production in two-photon processes at TRISTAN. The mean √s was 58 GeV and the integrated luminosity was 199 pb⁻¹. High-statistics Kₛ samples were obtained under such conditions as no-, anti-electron, and remnant-jet tags. The remnant-jet tag, in particular, allowed us, for the first time, to measure the cross sections separately for the resolved-photon and direct processes.
