Abstract
Data taken with the ALEPH detector at LEP1 have been used to search for /γγ production of the glueball candidates f0(1500) and fJ(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 fJ(1710) have been measured to beΓ(γγ-- >f0(1500)).BR(f0(1500)-- >π+π-)<0.31keV and Γ(γγ-- >fJ(1710)).BR(fJ(1710)-- >π+π-)<0.55keV at 95% confidence level.
