Abstract

The processes e+e-→Σ0Σ¯0 and e+e-→Σ+Σ- are studied using initial-state-radiation events in a sample of 980 fb-1 collected with the Belle detector at the KEKB asymmetric-energy e+e- collider. 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.
