N2 - Using a sample of 1.31×109 J/ψ events collected by the BESIII detector at BEPCII during 2009 and 2012, we study the J/ψ→ωη′π+π- hadronic process. For the first time, we measure the branching ratio B(J/ψ→ωη′π+π-)=(1.12±0.02±0.13)×10-3. We search for the X(1835) state in the η′π+π- invariant mass spectra. No evidence is found and we estimate the upper limit on the branching fraction at 90% confidence level to be B(J/ψ→ωX(1835),X(1835)→η′π+π-)<6.2×10-5.
