Abstract

We estimate the branching ratio and argue that two-gluino bound states can be detected in ϒ→γ+1S0(g~ g~) if mg~<4.5 GeV. The signal would be comparable to the backgrounds in magnitude. In the case of top-quarkonium decay, the signal could be much enhanced due to the exchange of a possibly light scalar top quark. We also show that two-gluino bound states can exist only in 1S0,3P0,1,2, 1D2, 3F2,3,4,..., but not in 3S1, 1P1, 3D1,2,3, 1F3,... states. The decay width of the g~ g~ ground state is calculated. Finally, we discuss the g~g~ potential.
