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 wi...
