In particle physics, a gaugino is the hypothetical superpartner of a gauge boson, as predicted by gauge theory combined with supersymmetry. They are fermions.
In the minimal supersymmetric extension of the standard model the gauginos are
- gluino is the superpartner of the gluon, and hence carries colour charge.
- wino is the superpartner of the W boson.
- bino is the superpartner of the gauge boson corresponding to weak hypercharge. It mixes with one of the gauginos corresponding to weak isospin to give the photino and the zino.
- zino is the superpartner of the Z boson.
- photino is the superpartner of the photon.
In supergravity theories, the superpartner of a graviton is the gravitino.
Gauginos mix with higgsinos to form linear combinations ("mass eigenstates") called neutralinos (neutral) and charginos (charged). Since the lighest neutralino is stable, it is a WIMP and a candidate for dark matter.
