The cross sections from the mass threshold to 3 GeV/c2 and the effective form factors of ς0 and ς+ are measured. In the charmonium region, we observe the decays J/ψ→ς0ς¯0 and J/ψ→ς+ς¯- and determine the respective branching fractions.14 page(s)application/pdfenIn CopyrightScience & TechnologyPhysical SciencesAstronomy & AstrophysicsPhysics, Particles & FieldsPhysicsP(P)OVER-BARE(+)E(-)5106 Nuclear and Plasma Physics5107 Particle and High Energy Physics51 Physical SciencesArticle - Refereedhttps://doi.org/10.1103/PhysRevD.107.0720081077Piilonen, Leo [0000-0001-6836-0748]2470-0029
