Abstract

Using data samples corresponding to an integrated luminosity of 0.9 fb − 1 collected with the BESIII detector operating at the BEPCII storage ring at the center-of-mass energies of 4.84, 4.92, and 4.95 GeV, we search for the exotic charmoniumlike state with quantum numbers J P C = 0 − − , ψ 0 ( 4360 ) , in the process e + e − → η ψ 0 ( 4360 ) with ψ 0 ( 4360 ) → η ψ ( 2 S ) . No significant signal of the ψ 0 ( 4360 ) resonance state is observed. Upper limits on σ ( e + e − → η ψ 0 ( 4360 ) ) · B ( ψ 0 ( 4360 ) → η ψ ( 2 S ) ) and σ ( e + e − → η η ψ ( 2 S ) ) at the 90% confidence level are determined for each energy point.
