supersymmetry
subject			fact

supersymmetry	has definition A symmetry relating fermions and bosons. If supersymmetry is a true symmetry of nature, then every "ordinary" particle has a corresponding "superpartner" which differs in spin by half a unit.
	has definition A symmetry principle that relates the properties of particles with a whole number amount of spin (bosons) to those with half a whole (odd) number amount of spin (fermions).
	has definition A symmetry that relates the fermions (fractional spin particles) to the bosons (elementary particles with integral spin).
	has definition Class of theories that seek to identify symmetrical relationships linking fermions and bosons - i.e., particles of half integer spin, like electrons, protoins, and neutrinos, with those of integral spin, like photons and gluons. If attainable, a fully realized supersymmetry theory would provide a unified account of all four fundamental forces, and might well shed light on the very early evolution of the universe as well.
	has definition A mathematical property of some theories of physics proposing that every particle of integer spin (intrinsic angular momentum) has a partner of half integer spin. For example, the photon, which is the particle of light, has a spin of 1 unit. Its hypothesized super symmetric partner is called the photino, which would have a spin of 1/2 units.
	is a kind of unified theory
theory	has validity correct or incorrect with caveats
	has author or reasearch group
	has domain a field of research
	has date or a range of dates for which the theory was active

Kinds of supersymmetry :

• supergravity (2 kinds, 7 facts) - A supersymmetric theory of gravity in which the graviton is accompanied by a spin-3/2 particle called the "gravitino". In supergravity theories, supersymmetry has been promoted to the status of a local gauge symmetry., Class of point-particle theories combining general relativity and supersymmetry
• supersymmetric quantum field theory (2 facts) - Quantum field theory incorporating supersymmetry.
• supersymmetric standard model (2 facts) - Generalization of the standard model of particle physics to incorporate supersymmetry. Entails a doubling of the known elementary particle species.
