Abstract
Data taken with the ALEPH detector at LEP have been used to study γγ production of the glueball candidate f o(1500) via its decay to π+π-. NO events were observed in excess of background and an upper limit to the γγ width of the f o(1500) has been calculated.
The first observation of f j (2220) production in hadronic Z decays in the L3 detector is also presented. A signal in the K os K os channel is observed in the least energetic jet of three-jet events.
