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.[1][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:
C͂± 2 → C͂± 1 + Z0
C͂± 2 → N͂0 2 + W±
C͂± 1 → N͂0 1 + W±
