Abstract
Data taken with the ALEPH detector at LEP1 have been used to search for γγ production of the glueball candidates f 0(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 f 0(1500) and the f J (1710) have been measured to be Γ(γγ→f 0(1500))· B R(f 0(1500)→π +π −)<0.31 keV and Γ(γγ→f J(1710))· B R(f J(1710)→π +π −)<0.55 keV at 95% confidence level.
