Gauge Theories of the Yang-Mills Type  

In General > s.a. gauge theory; Wilson Loop.
* Idea: Gauge theories with a specific form for the action/equations of motion; The original type of gauge theory, and still the most widely used one.
* Evidence: The first direct evidence came with the 1973 discovery of flavor-changing neutral currents at CERN.

Classical Dynamics > s.a. Faddeev-Niemi Equations; gauge theory [including loop-based variables]; lattice gauge theory.
* Action: In terms of the curvature Fab of the Lie algebra-valued connection Aa ("tr" uses the metric on G),

S[A] = \(1\over2\)M dv gab gmn tr(Fam Fbn) = # M tr(F ∧ *F).

* Field equations: They are the source equations, and

DF:= dF + [A, F] = 0 ,      D*F = J ;

the first one is the Bianchi identity, and the second is conformally invariant (masslessness; J is the source current).
* Matter fields: The coupling of the gauge field to matter is usually taken to be minimal; The free term "FF" is added to the matter Lagrangian, and all derivatives ∇ of matter fields are replaced by gauge-covariant derivatives D.
@ General references: Boozer AJP(11)sep [coupled particle-field system, 2D].
@ Action: Aldrovandi & Pereira RPMP(88) [existence of Lagrangians]; & Sengupta; Fine JMP(00)m.DG [lower bound on a Riemann surface]; Tolksdorf JGP(07) [form linear in the curvature]; Escalante & Berra IJPAM-a1301 [as a constrained BF-like theory].

Hamiltonian Formulation and Evolution > s.a. hamiltonian systems; solutions [singularities]; types of yang-mills theories [1+1 dimensions].
* Hamiltonian / Energy:

H(A, E) = d3x tr(E2 + B2) = # dv gab gmn tr(Fam Fbn) .

Other Issues and Effects > s.a. chaos in field theories; gauge theory solutions; QCD [confinement].
* Gauge choice: See Axial, Coulomb, Lorenz gauge.
* Mass generation: A possible mechanism is through a topological coupling of vector and tensor fields; After integrating over the tensor degrees of freedom, one arrives at an effective massive theory that is gauge invariant but non-local.
