Gaugino

In supersymmetry theories of particle physics, a gaugino is the hypothetical fermionic supersymmetric field quantum (superpartner) of a gauge field, as predicted by gauge theory combined with supersymmetry.

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

Gauginos mix[clarification needed] with higgsinos, the superpartners of the Higgs field's degrees of freedom, to form mass eigenstates called neutralinos, which are electrically neutral, and charginos, which are electrically charged.

In that case it is a weakly interacting massive particle (WIMP) and a candidate for dark matter.
