Chargino

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. 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 is 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±
