Is it farther or further?


[soo-per-sim-i-tree] /ˈsu pərˈsɪm ɪ tri/
noun, Physics.
a hypothetical symmetry among groups of particles containing fermions and bosons, especially in theories of gravity (supergravity) that unify electromagnetism, the weak force, and the strong force with gravity into a single unified force.

Examples from the web for supersymmetry
  • These would be evidence for an as yet hypothetical view of the world called supersymmetry.
  • Most important, string theory seems to require our world to have a property called supersymmetry.
  • Unbroken target space supersymmetry means existence of a constant spinor.
  • These were at the time studied almost exclusively in the context of supersymmetry.
  • Yet what ties the apparent dichotomy between internal and external symmetries is supersymmetry.
  • Contrast this to supersymmetry, which get increasingly disfavored by experiments as time goes by.
  • The discovery of supersymmetry would provide crucial evidence of a possible connection.
  • The detector will also be used for studies of top quark decays and supersymmetry searches.
  • Our theorists work on a wide range of subjects from quantum chromodynamics to supersymmetry and neutrino physics.

supersymmetry in Science
A theory of physics that states that for each boson (a subatomic particle that carries a fundamental force, such as the photon, which carries the electromagnetic force) there is a corresponding fermion with the same mass. The theory is an attempt to unify the fundamental forces of matter under one theory. Supersymmetry has not been shown to hold in the real world, though some scientists suspect that evidence for it may be found only at extremely high energies; some also believe that certain particles predicted by the theory may make up dark matter.

Encyclopedia Article for supersymmetry

in particle physics, a symmetry between fermions (subatomic particles with half-integer values of intrinsic angular momentum, or spin) and bosons (particles with integer values of spin). Supersymmetry is a complex mathematical framework based on the theory of group transformations that was developed beginning in the early 1970s to understand at a more-fundamental level the burgeoning number of subatomic particles being produced in high-energy particle accelerator experiments. It has evolved to address internal inconsistencies that arose in attempts to unify the forces in the Standard Model of particle physics. Supersymmetry is an essential feature of supergravity, the quantum field theory of the gravitational force, and of string theory, an ambitious attempt to provide a self-consistent quantum theory unifying all particles and forces in nature.
