Abstract
- The cross sections for the reactions e+e−→ϕη, ϕη′, ρη, ρη′ have been measured using a data sample of 516 fb−1 collected with the Belle detector at the KEKB asymmetric-energy e+e− collider. The corresponding values of the cross sections are: 1.4±0.4±0.1 fb (ϕη), 5.3±1.1±0.4 fb (ϕη′), 3.1±0.5±0.1 fb (ρη) and 3.3±0.6±0.2 fb (ρη′). The energy dependence of the cross sections is presented using Belle measurements together with those of CLEO and BaBar.
