Abstract
We report the first, kinematically-complete measurement of the differential cross section of Ï-meson photoproduction from deuterium near the production threshold for a proton using the CLAS detector and a tagged-photon beam in Hall B at Jefferson Lab. The measurement was carried out by a triple coincidence detection of a proton, K+ and Kâ near the theoretical production threshold of 1.57 GeV. The extracted differential cross sections dÏdt for the initial photon energy range of 1.65-1.75 GeV are consistent with predictions based on a quasifree mechanism. Our finding is different from recent LEPS results on Ï-meson photoproduction from deuterium in a similar incident photon energy range, but in a different momentum transfer region.
