Résumé

Data taken with the ALEPH detector at LEP1 have been used to search for γγ production of the glueball candidates f₀(1500) and f(J)(1710) via their decay to π⁺π^-. No signal is observed and upper limits to the product of γγ width and π⁺ π^- branching ratio of the f₀(1500) and the f(J)(1710) have been measured to be Γ(γγ→f₀(1500)) · BR(f₀(1500) → π⁺π^-) < 0.31 keV and Γ(γγ → f(J)(1710)) · BR(f(J)(1710) → π⁺π^-) < 0.55 keV at 95% confidence level.
