Název v původním jazyce

The investigation of strangeness photoproduction in the threshold region at ELPH-Tohoku

Popis výsledku v původním jazyce

The strangeness photoproduction processes near the threshold have been intensively studied by measuring K+ in reactions such as gamma + p -> K+ + Lambda(Sigma(0)). 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 gamma + d -> K-0 (Lambda) + X reaction in the pi(+)pi(-) (p pi(-)) decay channel of K-S(0) (Lambda) using a liquid D-2 target and internally-tagged photon beams (E gamma =0.80-1.08 GeV) at Research Center for Electron Photon Science (ELPH), Tohoku University. We have renewed the spectrometer (NKS2) and took data with a liquid D-2 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 Lambda 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-sect
