Шаблон:More footnotes Шаблон:Standard model of particle physics 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. All gauginos have a spin of 1/2, except for the gravitino, which has a spin of 3/2.

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 (Шаблон:SubatomicParticle) is the superpartner of the Z boson.

Mixing

Gauginos mixШаблон:Clarify 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 many supersymmetric modelsШаблон:Clarify, 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.Шаблон:Elucidate
