WebIt is shown that the theory of the neutral vector field with nonzero rest mass may be formulated in a gauge-invariant form without introducing auxiliary fields. The gauge invariance in such a theory has a trivial physical meaning: the zero spin quanta described by a four-vector A/sub mu /interact with nothing. Only the quanta with spin 1 interact.

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. In electrostatics, one can either discuss the electric field, E, or its corresponding electric potential, V. Knowledge of one … See more Gauge theories may be quantized by specialization of methods which are applicable to any quantum field theory. However, because of the subtleties imposed by the gauge constraints (see section on Mathematical formalism, above) there are … See more Global and local symmetries Global symmetry In physics, the mathematical description of any physical … See more Gauge theories are usually discussed in the language of differential geometry.
