=== Supersymmetry ===
{{Main|Supersymmetry}}

Supersymmetry extends the Standard Model by adding another class of symmetries to the [[Lagrangian (field theory)|Lagrangian]]. These symmetries exchange [[fermion]]ic particles with [[boson]]ic ones. Such a symmetry predicts the existence of [[supersymmetric particle]]s, abbreviated as ''[[sparticle]]s'', which include the [[slepton]]s, [[squark]]s, [[neutralino]]s, and [[chargino]]s. Each particle in the Standard Model would have a superpartner whose [[Spin (physics)|spin]] differs by {{1/2}} from the ordinary particle. Due to the [[supersymmetry breaking|breaking of supersymmetry]], the sparticles are much heavier than their ordinary counterparts; they are so heavy that existing [[particle collider]]s would not be powerful enough to produce them. Some physicists believe that sparticles will be detected by the [[Large Hadron Collider]] at [[CERN]].
