Based on (2712.4±14.3)×106 events recorded at the ψ(3686) nominal mass collected with the BESIII detector operating at the BEPCII collider, the ψ(3686)→Σ+¯Σ−ω and Σ+¯Σ−ϕ decays are observed for the first time with statistical significances of 13.8σ and 7.6σ, respectively. The corresponding branching fractions are measured to be B(ψ(3686)→Σ+¯Σ−ω)=(1.89±0.18±0.21)×10−5 and B(ψ(3686)→Σ+¯Σ−ϕ)=(2.96±0.54±0.41)×10−6, where the first uncertainties are statistical and the second systematic.
