| dc.description | The production of the χ_{c2} charmonium state in two-photon collisions has been measured with the Belle detector at the KEKB e^+e^- collider. A clear signal for χ_{c2} --> γJ/ψ, J/ψ--> l^+l^- is observed in a 32.6fb^{-1} data sample accumulated at center-of-mass energies near 10.6GeV, and the product of its two-photon decay width and branching fraction is determined to be Γ_{γγ}(χ_{c2})B(χ_{c2} --> γJ/ψ) B(J/ψ--> l^+l^-)= 13.5 +/- 1.3(stat.) +/- 1.1(syst.)eV. | |
