摘要
Data taken with the ALEPH detector at LEP1 have been used to search for gamma gamma production of the glueball candidates f(0)(1500) and f(J)(1710) via their decay to pi (+)pi (-). No signal is observed and upper limits to the product of gamma gamma width and pi (+)pi (-) branching ratio of the f(0)(1500) and the f(J)(1710) have been measured to beGamma>(*) over bar *(gamma gamma --> f(0)(1500)) . BR(f(0)(1500) --> pi (+)pi (-)) < 0.31 keV(gamma gamma --> f(J)(1710)) . BR(f(J)(1710) --> pi (+)pi (-)) < 0.55 keV at 95% confidence level.
