Le chargino est une particule supersymétrique hypothétique. Il se rapporte à l'état propre de masse du superpartenaire chargé, i.e. n'importe quel fermion chargé électriquement (de spin 1/2) prédit par la supersymétrie. Ils sont des combinaisons linéaires des winos et des higgsinos chargés.

Superpartenaire

En physique des particules, le superpartenaire est une particule virtuelle appariée par la supersymétrie. À chaque particule est associée un superpartenaire. Les propriétés du superpartenaire sont tout à fait semblables à la particule qui lui est associée, excepté son spin : celui du superpartenaire diffère de son associé d'une demi-unité. Autrement dit, chaque particule de spin 1/2 est associée à un superpartenaire de spin 0 ; chaque particule de spin 1 est associée à une particule de spin 1/2.

Minimal Supersymmetric Standard Model

The Minimal Supersymmetric Standard Model (MSSM) is an extension to the Standard Model that realizes supersymmetry. MSSM is the minimal supersymmetrical model as it considers only "the [minimum] number of new particle states and new interactions consistent with "Reality". Supersymmetry pairs bosons with fermions, so every Standard Model particle has a superpartner yet undiscovered. If discovered, such superparticles could be candidates for dark matter, and could provide evidence for grand unification or the viability of string theory.
