  2. Supersymmetry - Wikipedia

    en.wikipedia.org/wiki/Supersymmetry

    Supersymmetry is an integral part of string theory, a possible theory of everything. There are two types of string theory, supersymmetric string theory or superstring theory, and non-supersymmetric string theory. By definition of superstring theory, supersymmetry is required in superstring theory at some level.

  3. Supersymmetric quantum mechanics - Wikipedia

    en.wikipedia.org/wiki/Supersymmetric_quantum...

    To make progress on these problems, physicists developed supersymmetric quantum mechanics, an application of the supersymmetry superalgebra to quantum mechanics as opposed to quantum field theory. It was hoped that studying SUSY's consequences in this simpler setting would lead to new understanding; remarkably, the effort created new areas of ...

  4. Supersymmetric theory of stochastic dynamics - Wikipedia

    en.wikipedia.org/wiki/Supersymmetric_Theory_of...

    The first relation between supersymmetry and stochastic dynamics was established in two papers in 1979 and 1982 by Giorgio Parisi and Nicolas Sourlas, [1] [2] who demonstrated that the application of the BRST gauge fixing procedure to Langevin SDEs, i.e., to SDEs with linear phase spaces, gradient flow vector fields, and additive noises, results in N=2 supersymmetric models.

  5. Hierarchy problem - Wikipedia

    en.wikipedia.org/wiki/Hierarchy_problem

    Without supersymmetry, a solution to the hierarchy problem has been proposed using just the Standard Model. The idea can be traced back to the fact that the term in the Higgs field that produces the uncontrolled quadratic correction upon renormalization is the quadratic one.

  6. Physics beyond the Standard Model - Wikipedia

    en.wikipedia.org/wiki/Physics_beyond_the...

    Supersymmetry extends the Standard Model by adding another class of symmetries to the Lagrangian. These symmetries exchange fermionic particles with bosonic ones. Such a symmetry predicts the existence of supersymmetric particles , abbreviated as sparticles , which include the sleptons , squarks , neutralinos and charginos .

  7. N = 4 supersymmetric Yang–Mills theory - Wikipedia

    en.wikipedia.org/wiki/N_=_4_supersymmetric_Yang...

    In D=4 spacetime dimensions, N=4 is the maximal number of supersymmetries or supersymmetry charges. [1] SYM theory is a toy theory based on Yang–Mills theory; it does not model the real world, but it is useful because it can act as a proving ground for approaches for attacking problems in more complex theories. [2]

  9. Superspace - Wikipedia

    en.wikipedia.org/wiki/Superspace

    Superspace is the coordinate space of a theory exhibiting supersymmetry.In such a formulation, along with ordinary space dimensions x, y, z, ..., there are also "anticommuting" dimensions whose coordinates are labeled in Grassmann numbers rather than real numbers.
