Supersymmetry relates fundamental particles so that each one has a superpartner, or "sparticle.". The two types of particles involved are bosons and fermions. Fermions carry half-integer spins (intrinsic angular momentum) and two fermions in the same state cannot occupy only one space at one time. In the Standard Model of particle physics, the matter particles, quarks and leptons, are fermions. The force-carriers in the Standard Model are bosons. Bosons are particles that carry integer spins and even being in the same state can gather in a single space at the same time. Supersymmtry changes a fermion into boson, i.e. each fermion has a supersymmetric partner which is a boson, and vise versa. Supersymmetry shows potential at unifying the four fundamental forces.

Feynman Diagrams show collisions of particles and are used to calculate how likely it is that a certain collision is observed. The Feynman diagrams in the exhibit show the production of supersymmetric particles at a particle collider such as the Fermilab Tevatron and the CERN Large Hadron Collder (LHC). Solid lines represent fermions, dashed lines for bosons, spiraling lines for gluons, and wavy lines for photons and weak force carriers.
