In supersymmetry theories of

In the minimal supersymmetric extension of the standard model the following gauginos exist:

• The gluino (symbol
  g͂
  ) is the superpartner of the gluon, and hence carries color charge.
• The gravitino (symbol
  G͂
  ) is the supersymmetric partner of the graviton.
• Three winos (symbol
  W͂^±
  and W͂³) are the superpartners of the
  W bosons
  of the SU(2)_L gauge fields.
• The bino is the superpartner of the U(1) gauge field corresponding to weak hypercharge.

Sometimes the term "electroweakinos" is used to refer to winos and binos and on occasion also higgsinos.^[1] Note that in other SUSY models the zino (
Z͂
) is the superpartner of the Z boson.

, which are electrically charged.

In many supersymmetric models^[clarification needed], the lightest supersymmetric particle (LSP), often a neutralino such as the photino, is stable. In that case it is a weakly interacting massive particle (WIMP) and a candidate for dark matter.^{[further explanation needed]}
