Abstract: (Elsevier)
A search has been made for the production of a charmonium state χ c 2 in two-photon processes. We have used the decay channel χ c 2 → γ J/ ψ , J/ ψ →ℓ + ℓ − . No signal enhancement indicating the production of χ c2 has been observed in the invariant mass distributions of the final state particles, and an upper limit for the two-photon decay width, Γ γγ ( χ c2 )<4.2 keV at 95% CL, has been obtained.
