Study of inclusive J/psi production in two-photon collisions at LEP II with the DELPHI detector

Inclusive J/ψ production in photon-photon collisions has been observed at LEP II beam energies. A clear signal from the reaction γγ → J/ψ + X is seen. The number of observed N(J/ψ → μ+μ-) events is 36 ± 7 for an integrated luminosity of 617 pb-1, yielding a cross-section of σ(J/ψ + X) = 45 ± 9(stat)...
