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.

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

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:
