Gauge theory in particle physics
Did you know?
In physics, a gauge theory is a type of field theory in which the Lagrangian (and hence the dynamics of the system itself) does not change (is invariant) under local transformations according to certain smooth families of operations (Lie groups). The term gauge refers to any specific mathematical … See more The earliest field theory having a gauge symmetry was Maxwell's formulation, in 1864–65, of electrodynamics ("A Dynamical Theory of the Electromagnetic Field") which stated that any vector field whose curl vanishes—and … See more Classical electromagnetism Historically, the first example of gauge symmetry discovered was classical electromagnetism See more Gauge theories may be quantized by specialization of methods which are applicable to any quantum field theory. However, because … See more A pure gauge is the set of field configurations obtained by a gauge transformation on the null-field configuration, i.e., a gauge transform of zero. So it is a particular "gauge orbit" in the field configuration's space. Thus, in the abelian … See more Global and local symmetries Global symmetry In physics, the mathematical description of any physical situation usually contains excess See more Gauge theories are usually discussed in the language of differential geometry. Mathematically, a gauge is just a choice of a (local) section of some principal bundle. A gauge transformation is just a transformation between two such sections. Although gauge … See more • Gauge principle • Aharonov–Bohm effect • Coulomb gauge • Electroweak theory • Gauge covariant derivative See more Webparticle physics are gauge theories. The classical example of a gauge theory is Maxwell’s theory of electromagnetism. For electromagnetism the gauge symmetry group is the abelian group U(1). If Adenotes the U(1) gauge connection, locally a one-form on space-time, then the curvature or electromagnetic field tensor is the

These forces transmit their influence through particles called gauge bosons. String theory allows gravity to be expressed in terms of a gauge theory, which is one of its benefits. cle to telluride flightsHistorically, the first example of gauge symmetry to be discovered was classical electromagnetism. A static electric field can be described in terms of an electric potential (voltage, ) that is defined at every point in space, and in practical work it is conventional to take the Earth as a physical reference that defines the zero level of the potential, or ground.
