Recent results from LEPS and prospects of LEPS II at SPring-8

摘要

SPring-8/LEPS is a GeV photon beam facility for hadron physics. The linearly polarized photon beam is produced by backward-Compton scattering of laser photons from 8 GeV electrons. We have studied photoproduction of hadrons which contain strange quarks. In this article, firstly, we report one of the recent results from LEPS, the κ(800) meson search in the yp → K~(*0)Σ~+ reaction. Secondly, the status of the construction of a new GeV photon beam line LEPS II is described.
