Supersymmetry
Advanced
Proposed symmetry connecting bosons and fermions.
Proposes a partner for each particle differing in spin by ½ (selectron, gluino). It could solve the hierarchy problem and provide dark matter, but the LHC hasn't found it so far.
Neutralino as a WIMP candidate.
Constrained by experiments.
In more detail
Supersymmetry proposes a partner particle for each known particle, differing in spin by one half. It could solve problems in the Standard Model and provide candidates for dark matter.
Real-world uses
- Supersymmetry is a major target for searches at the LHC.
- Dark matter candidates are predicted in some supersymmetric models.
- Experimental physicists search the LHC data for superpartners of known particles, which would show supersymmetry.

Frequently asked questions
Has supersymmetry been found?
No evidence has been found so far at the LHC.
Why is it attractive?
It can stabilise the Higgs mass and provide dark matter candidates.
Why do physicists like supersymmetry?
It could solve several problems in the Standard Model and provide candidates for dark matter, but no evidence has yet been found.
