We calculate the differential cross sections of the gamma +D -> Lambda + Theta+, gamma + D -> Sigma + Theta+ and relevant background reactions in the photon energy range 1.2 < E_{\\gamma} < 2.6 GeV. We determine the most favorable kinematic conditions and observables for the experimental studies of Theta+ in the considered processes. We argue that a comparison of the gamma + D -> Lambda + Theta+ and gamma + D -> Sigma + Theta+ cross sections should unambiguously determine isospin of Theta+.", "revisions": [ { "version": "v2", "updated": "2004-06-28T12:33:25.000Z" } ], "analyses": { "subjects": [ "25.20.Lj", "13.60.Rj", "14.20.Jn" ], "keywords": [ "production", "differential cross sections", "relevant background reactions", "photon energy range", "unambiguously determine isospin" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
