Lightest supersymmetric particle

In particle physics, the lightest supersymmetric particle (LSP) is the generic name given to the lightest of the additional hypothetical particles found in supersymmetric models. In models with R-parity conservation, the LSP is stable; in other words, it cannot decay into any Standard Model particle, since all SM particles have the opposite R-parity. There is extensive observational evidence for an additional component of the matter density in the universe, which goes under the name dark matter.

Jaugino

En physique des particules, un jaugino (graphie anglaise gaugino) est le superpartenaire hypothétique d'un boson de jauge, prévu par la théorie de jauge combiné avec la supersymétrie. Ce sont des fermions. Dans l'extension supersymétrique minimale du modèle standard, les jauginos sont : le gluino est le superpartenaire du gluon, et par conséquent porte une charge de couleur ; le wino est le superpartenaire du boson W ; le xino est le superpartenaire du boson X ; le yino est le superpartenaire du boson Y ; le bino est le superpartenaire du boson de jauge correspondant à l'hypercharge faible.

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.
