چکیده انگلیسی
The strangeness photoproduction processes near the threshold have been intensively studied by measuring K+ in reactions such as γ+pâK++Î(Σ0). There has been no reliable data on the neutron and as a consequence theoretical investigation suffered seriously from the lack of the data. We have an effort to measure the γ+dâK0(Î)+X reaction in the Ï+Ïâ (pÏâ) decay channel of KS0 (Î) using a liquid D2 target and internally-tagged photon beams (Eγ=0.80-1.08GeV) at Research Center for Electron Photon Science (ELPH), Tohoku University. We have renewed the spectrometer (NKS2) and took data with a liquid D2 target in 2005-2007. More recently, we took data in 2010 after a detector upgrade in the vertex region to substantially increase the acceptance. The results of Î single measurements on a deuterium target were obtained for differential cross-section as a function of momentum, as a function of angle, and integrated cross-section as a function of beam energy. The results are compared with recent theoretical studies: Isobar models (Kaon-MAID and Saclay-Lyon A) and a Regge-plus-Resonance model.
