Abstract

Using a sample of 102×106 Υ(1S) events collected with the Belle detector, we report on the first search for charge-parity-even charmonium and charmoniumlike states in Υ(1S) radiative decays. No significant χcJ or ηc signal is observed and 90% C.L. limits on B(Υ(1S)→γχc0)<6.5×10⊃-4, B(Υ(1S)→γχc1)<2.3×10⊃-5, B(Υ(1S)→γχc2)<7.6×10⊃-6, and B(Υ(1S)→γηc)<5.7×10⊃-5 are obtained. The product branching fraction limits B(Υ(1S)→γX(3872)) B(X(3872)→π⊃+π⊃-J/ψ)<1.6×10⊃-6, B(Υ(1S)→γX(3872))B(X(3872)→π⊃+π⊃-π0J/ ψ)<2.8×10⊃-6, B(Υ(1S)→γX(3915))B(X(3915) →ωJ/ψ)<3.0×10⊃-6, and B(Υ(1S) →γY(4140))B(Y(4140)→J/ψ)<2.2×10⊃-6 are obtained at the 90% C.L. Furthermore, no evidence is found for excited charmonium states below 4.8GeV/c2.
