Search for the glueball candidates f/sub 0/(1500) and f/sub J/(1710) in gamma gamma collisions

Summary form only given. Data taken with the ALEPH detector at LEP1 have been used to search for gamma gamma production of the glueball candidates f/sub 0/(1500) and f/sub J/(1710) via their decay to pi /sup +/ pi /sup -//sub ./ No signal is observed and upper limits to the product of gamma gamma width and pi /sup +/ pi /sup b/ranching ratio of the f/sub 0/(1500) and the f/sub J/(1710) have been measured to be Gamma ( gamma gamma to f/sub 0/(1500)) BR(f/sub 0/(1500) to pi /sup +/ pi /sup -/) < 0 31keV and Gamma ( gamma gamma to f/sub J /(1710)) BR(f/sub J/(1710) to pi /sup +/ pi /sup -/) < 0 55keV at 95% confidence level.
