Gluinonia: Energy levels, production and decay Original Research Article

Predictions for energy levels, production and decay rate of gluinonia, non-relativistic bound states of gluinos, are presented. The potential between color-octet constituents is derived in next-to-next-to-leading order and one-loop QCD corrections are derived for the production cross section and the decay rate into gluon jets. In addition we evaluate the decay rate into top quarks and into two photons. The signal-to-background ratio is estimated for the dominant decay mode and found to be around 0.5%. For relatively light gluinos the bound states thus might be detectable.
