After the Higgs, LHC Rounds Up the Unusual Suspects in Particle Physics

The new phenomena could take the form of supersymmetric particles, as-yet-undetected bits of matter that would add an elegant twist to the Standard Model. One such particle could be agluino, the supersymmetric partner of a known particle called the gluon.
Other hypothesized supersymmetric particles include neutralinos, which could account for the universe's mysterious dark matter; and gravitinos, which could help explain dark matter as well as some of the mysteries surrounding gravity. The discrepancies also could be caused by anew breed of fourth-generation quark, Heinemann said.
