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 ${\tilde{\chi }}_1^{\pm }$ and ${\tilde{\chi }}_2^{\pm }$ are also used to refer to charginos, when ${\tilde{\chi }}_i^0$ 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 →

₁ +
