Chargino

Template:Short description Template:Standard model of particle physics 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.<ref>Template:Cite book</ref><ref>Template:Cite journal</ref> 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 Template:SubatomicParticle (the lightest) and Template:SubatomicParticle (the heaviest), although sometimes <math>\tilde{\chi}_1^\pm</math> and <math>\tilde{\chi}_2^\pm</math> are also used to refer to charginos, when <math>\tilde{\chi}_i^0</math> 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:

Template:SubatomicParticle → Template:SubatomicParticle + Template:SubatomicParticle

Template:SubatomicParticle → Template:SubatomicParticle + Template:SubatomicParticle
