Abstract

Using a sample of 158 × 106 γ(2S) events collected with the Belle detector, charmonium and charmoniumlike states with even charge parity are searched for in γ(2S) radiative decays. No significant XcJ or ηc signal is observed, and the following upper limits at 90% confidence level (C. L.) are obtained: B(γ(2S) γXc0)< 1:0 × 10-4, B(γ(2S) γXc1) < 3:6 × 10-6, B(γ(2S) γXc2) < 1:5 × 10-5, and B(γ(2S) γηc) < 2:7 × 10-5. No significant signal of any charmoniumlike state is observed, and we obtain the limits B(γ(2S) γX(3872)) X B(X(3872) π+π- J/ψ)<0.8 × 10-6, B(γ(2S) γX(3872))X B(X(3872) π+π-π0J/ψ)<2:4 × 10-6, B(γ(2S) γX(3915)) X B(X(3915) ωJ/ψ)<2:8 × 10-6, B(γ(2S) γY(4140)) X B(Y(4140) ΦJ/ψ)) < 1:2 × 10-6, and B(γ(2S) γX(4350)) X B(X(4350) ΠJ/ψ) < 1:3 × 10-6 at 90% C. L.
