abstract = "Using a sample of (10087±44)×106 J/ψ events collected by the BESIII detector at the BEPCII collider, we search for the decay X(1870)→K+K-η via the J/ψ→ωK+K-η process for the first time. No significant X(1870) signal is observed. The upper limit on the branching fraction of the decay J/ψ→ωX(1870)→ωK+K-η is determined to be 9.55×10-7 at the 90\% confidence level. In addition, the branching faction B(J/ψ→ωK+K-η) is measured to be (3.33±0.02(stat)±0.12(syst))×10-4.",
