A gluino (symbol g͂) is the hypothetical supersymmetric partner of a gluon. Gluinos are expected by supersymmetry theorists to be pair produced in particle accelerators such as the Large Hadron Collider if they exist.
Gluinos decay via strong interaction to a squark and a quark provided that an appropriate mass relation is satisfied. The squark subsequently decays to another quark and the lightest supersymmetric particle, LSP (which leaves the detector unseen). This means that a typical signal for a gluino at a hadron collider would be four jets plus missing energy.
However if gluinos are lighter than squarks, 3-body decay of a gluino to a neutralino and a quark antiquark pair is kinematically accessible through an off-shell squark.
- As there are 8 gluons of different color combinations, there are 8 gluinos of different color combinations, too.
