- A set of selection criteria has been elaborated using Monte-Carlo modeling simulation (MC) to extract the ω→ηe+e- decay events. Using a data sample of 6 pb-1 collected in 3 central points in the energy range close to ω-meson invariant mass the upper limit on the branching ratio of decay has been estimated: B(ω→ηe+e-) < 5 ∙ 10-6, which does not contradict to the Vector Dominance Model (VDM) prediction: (2.0 – 4.8) ∙ 10-6.
