(extension to standard model of particle physics)

Supersymmetry (SUSY) is a particular type of extension to the standard model of particle physics that theorizes an additional set of leptons and bosons with an additional lepton corresponding to each known boson and vice versa. The additional particles (superparticles) would have a spin quantum number which is 1/2 different from the corresponding known particle. Some superparticle terms:

known lepton supersymmetric boson
quark squark
neutrino sneutrino
electron selectron
muon smuon
tau stau
known boson supersymmetric lepton
gluon gluino
photon photino
Z boson zino
W boson wino
Higgs boson Higgsino

Neutralinos would be a result of quantum mixing of some of the superparticles.

Supergravity (SUGRA) is a supersymmetry theory variant that also incorporates general relativity.
