Information About

Gaugino




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 Higgsino s to form linear combinations ("mass eigenstates") called Neutralino s (neutral) and Chargino s (charged). Since the lighest neutralino is stable, it is a WIMP and a candidate for Dark Matter .
