  2. Supersymmetric gauge theory - Wikipedia

    en.wikipedia.org/wiki/Supersymmetric_gauge_theory

    A local symmetry is a symmetry which is position dependent. Gauge symmetry is an example of a local symmetry, with the symmetry described by a Lie group (which mathematically describe continuous symmetries), which in the context of gauge theory is called the gauge group of the theory.

    The same can happen in other gauge theories. In the broken phase the fluctuations of the scalar field will manifest themselves as a naturally light Higgs boson, as a matter of fact even too light to explain the electroweak symmetry breaking in the minimal model - much lighter than vector bosons. There are non-minimal models that give a more ...

  4. Introduction to gauge theory - Wikipedia

    en.wikipedia.org/wiki/Introduction_to_gauge_theory

    A gauge theory is a type of theory in physics.The word gauge means a measurement, a thickness, an in-between distance (as in railroad tracks), or a resulting number of units per certain parameter (a number of loops in an inch of fabric or a number of lead balls in a pound of ammunition). [1]

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

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

    The components of the gauge field for i = 4 to 9 become scalars upon eliminating the extra dimensions. This also gives an interpretation of the SO(6) R-symmetry as rotations in the extra compact dimensions. By compactification on a T 6, all the supercharges are preserved, giving N = 4 in the 4-dimensional theory.

  6. Gauge symmetry (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Gauge_symmetry_(mathematics)

    A gauge symmetry of a Lagrangian is defined as a differential operator on some vector bundle taking its values in the linear space of (variational or exact) symmetries of . Therefore, a gauge symmetry of L {\displaystyle L} depends on sections of E {\displaystyle E} and their partial derivatives. [ 1 ]

  7. Super QCD - Wikipedia

    en.wikipedia.org/wiki/Super_QCD

    In theoretical physics, super QCD is a supersymmetric gauge theory which resembles quantum chromodynamics (QCD) but contains additional particles and interactions which render it supersymmetric. The most commonly used version of super QCD is in 4 dimensions and contains one Majorana spinor supercharge.

  8. N = 1 supersymmetric Yang–Mills theory - Wikipedia

    en.wikipedia.org/wiki/N_=_1_supersymmetric_Yang...

    In theoretical physics, more specifically in quantum field theory and supersymmetry, supersymmetric Yang–Mills, also known as super Yang–Mills and abbreviated to SYM, is a supersymmetric generalization of Yang–Mills theory, which is a gauge theory that plays an important part in the mathematical formulation of forces in particle physics.

  9. Gauge theory - Wikipedia

    en.wikipedia.org/wiki/Gauge_theory

    Quantum electrodynamics is an abelian gauge theory with the symmetry group U(1) and has one gauge field, the electromagnetic four-potential, with the photon being the gauge boson. The Standard Model is a non-abelian gauge theory with the symmetry group U(1) × SU(2) × SU(3) and has a total of twelve gauge bosons: the photon , three weak bosons ...
