In
particle physics, the chargino is a hypothetical particle which refers to the mass
eigenstates of a charged
superpartner, i.e. any new electrically charged
fermion (with
spin 1/2) predicted by
supersymmetry.

[2] They are
linear combinations of the charged
wino and charged
higgsinos. There are two charginos that are fermions and are electrically charged, which are typically labeled
C͂±
1 (the lightest) and
C͂±
2 (the heaviest), although sometimes and are also used to refer to charginos, when is used to refer to
neutralinos. The heavier chargino can decay through the neutral
Z boson to the lighter chargino. Both can decay through a charged W boson to a neutralino:
