The Hamiltonian formulation of the /ital Z/(2) gauge theory at spatial dimension 2 is analyzed in gauge-invariant geometric terms by working in the loop-labeled basis of the /ital C/ representation. A consistent behavior of physical quantities near the critical point and a reasonable estimation of the transition point and the critical ...
In this paper, the authors discuss Ward identities in five-dimensional Abelian Chern-Simons theory. Using the Ward identities the authors calculate correlation functions of some field variables which are invariant under diffeomorphisms and gauge transformations. The authors show that the correlation functions are expressed by the ...
In the context of the equivalent-boson method a large variety of quark- gluon theories are studied in two dimensions. A number of simple results are obtained, including the fact that gluon inteactions (Abelian and non-Abelian) leave most of the physical currents free (at zero quark mass). (AIP)
We review the string representations of Abelian-projected SU(2)- and SU(3)-gauge theories and their application to the evaluation of bilocal field strength correlators. The large distance asymptotic behaviours of the latter ones are shown to be in agreement with the Stochastic Vacuum Model of QCD and existing lattice data
In this paper we quantize massive Abelian two-form gauge fields in six dimensions following the antifield BRST formalism. The quantization procedure is based on the quantization of a first-class system associated with the original theory. This first-class system is obtained by converting the original second-class constraints into some ...
We demonstrate how to create artificial external non-Abelian gauge potentials acting on cold atoms in optical lattices. The method employs atoms with k internal states, and laser assisted state sensitive tunneling, described by unitary k x k matrices. The single-particle dynamics in the case of intense U2 vector potentials lead to a generalized Hofstadter ...

We derive the various forms of BRST symmetry using Batalin-Fradkin-Vilkovisky approach in the case of Abelian 2-form gauge theory. We show that the so-called dual BRST symmetry is not an independent symmetry but the generalization of BRST symmetry obtained from the canonical transformation in the bosonic and ghost sector. We further ...
There is a subtle difference between the open string dynamics determined by the original dual resonance models and that determined by D-brane constructions within critical closed string theory. For instance, in contrast to the former, the latter have massless scalars in addition to the massless gluon shared by both. We introduce and explain the concept of ...
Analytic and numerical studies of the lattice gauge theories with both Higgs and fermion fields are reported. A chiral transition is found in a wide class of such theories, both abelian and non-abelian. This transition separates each phase diagram into two regions, one with spontaneous chiral ...
The usual formalism for non-Abelian gauge theories is not completely satisfactory. Calculations show that the usual formalism for Weinberg's unified gauge theory with a bilinear gauge condition leads to violation of unitarity, contrary to general formal ...
We show that the N=1 supergravity theories in ten dimensions with gauge groups U(1){496} and E{8}�U(1){248} are not consistent quantum theories. Cancellation of anomalies cannot be made compatible with supersymmetry and Abelian gauge invariance. Thus, in ten dimensions all supersymmetric ...
Classical solutions of the self-interacting, non-abelian antisymmetric tensor gauge theory of Freedman and Townsend coupled to Einstein gravity are discussed. Particularly, it is demonstrated that the theory admits a classical metric solution which, depending on the value of the gauge coupling ...
Applying the dynamic shooting method, we proved the existence of nontopological radially symmetric n-vortex solutions to the self-dual equation in non-Abelian Chern-Simons gauge theory with a {Phi}{sup 2}-type potential. Moreover, we obtained all possible radially symmetric nontopological bare (or 0-vortex) solutions in the ...
The influence of vector backgrounds with restored Lorentz invariance on non-Abelian gauge field theories is studied. Lorentz invariance is ensured by taking the average over a Lorentz invariant ensemble of background vectors, which are shifting the gauge field. Thereby the propagation of fermions is suppressed over ...
We improve on a method to compute the fermion contribution to the vacuum polarization energy of string-like configurations in a non-Abelian gauge theory. We establish the new method by numerically verifying the invariance under (a subset of) local gauge transformations. This also provides further support for the ...
Investigations into the nature of possible mechanisms for the confinement of quarks and gluons are reported. Flux patterns in lattice gauge theories are studied with Monte Carlo techniques, and comparisons are made between Abelian and non-abelian theories. The flux patterns associated with the ...
The coupling of chiral fermions in a fundamental representation of SU(2) to a general set of spherically symmetric gauge fields is explored. A method patterned after that employed for the gauge fields is used to impose spherical symmetry on the spinor fields. When this is done, reduction of the Weyl-Dirac equations using the explicit spherical symmetry ...
We show that a gauge-invariant magnetic monopole can be defined in Yang-Mills theory without matter fields, using a non-Abelian Stokes theorem and change of field variables a la Cho-Faddeev-Niemi, instead of using the Abelian projection. In fact, we give a first exact solution representing a magnetic monopole loop ...
The considerations of the first paper in this series are extended to non- Abelian gauge models of the strong, weak, and electromagnetic interactions. It is shown that for a large class of such theories, the strong interactions naturally conserve parity and strangeness, and possibly isospin and other quantum numbers as well. ...
We study the effect of a Chern-Simons (CS) term in the phase structure of two different Abelian gauge theories. For the compact Maxwell-Chern-Simons theory, with the CS term properly defined, we obtain that for values g = n/2? of the CS coupling with n = �1, �2, the theory is equivalent to ...
The role which gauge transformations of noninteger winding numbers might play in non-Abelian gauge theories is studied. The phase factor acquired by the semiclassical physical states in an arbitrary background gauge field when they undergo a gauge transformation of an ...
In a topologically nontrivial gauge theory not all gauge transformations are symmetries (as defined by Forgacs and Manton and by Schwarz) of a given field configuration: first, there may be an obstruction to implement gauge transformations on the fields; next, even those transformations which can be implemented may ...
In this work, we propose a new non-Abelian generalization of the Born Infeld Lagrangian. It is based on a geometrical property of the Abelian Born Infeld Lagrangian in its determinantal form. Our goal is to extend the Abelian second-type Born Infeld action to the non-Abelian form preserving this geometrical ...
An infinite class of nonplanar skeleton graphs is found to vanish in any non-Abelian gauge theory. Thus, the dominance of planar graphs is enhanced, particularly in processes where some momenta are very large.
The t-expansion is a nonperturbative calculational tool recently developed for Hamiltonian systems. A short review of the method is given. It is followed by a summary of applications to two dimensional spin systems and to four dimensional non-abelian lattice gauge theories. 5 refs., 3 figs.
It is shown that the conserved magnetic and electric charges in non-Abelian theories have nothing to do with the Higgs scalars and/or the symmetry structure of the Lagrangian. They are a consequence of the local isospin gauge symmetry. Several exact stati...
The generalized renormalization group equations are used to analyze the dynamical mechanism of particle mass generation in the Cornwall--Norton model with and without cutoff. The solutions with nonzero physical masses of two fermions m sub 1 , m sub 2 and...
The radiative correction to the topological mass in a (2+1)-dimensional Abelian gauge theory is shown to vanish at two loops. We consider the general case of a nonzero tree-level topological mass, thus extending some recent work.
A shortcut is presented to derive the ghost propagator of a non-Abelian gauge theory in the background of a single magnetic string. The technique takes advantages of the fact that in cylindrical coordinates the presence of a magnetic string of strength (b...
A path-integral measure for left-handed fermions is constructed for non-Abelian gauge theories, and its properties under unitary transformations are discussed.
We introduce a new concept for thermal quantum theories, which expresses a time dependent quasi-particle picture as the coupling to an external (classical) gauge field. The non-abelian nature of this field even for quasi-free systems can lead to renormali...
In searching for tools to describe physical systems consisting of hadronic matter at high temperature, it is worthwhile to consider the application of classical chromodynamics. Classical non-Abelian gauge theories have been extensively studied and continu...
The concepts of instantons, multiple vacua and vacuum tunnelling are formulated in the canonical framework. This formalism enables one to give explicit expressions for previously unconsidered relations between the physical and unphysical sectors of the in...

The original the dual representation for abelian LGT's was constructed in [2]. Extensions to nonabelian groups have been
The Aharonov-Bohm effect has been invoked to probe the phase structure of a gauge theory. Yet in the case of non-Abelian gauge theories, it proves difficult to formulate a general procedure that unambiguously specifies the realization of the gauge symmetry, e.g., the ...
The formation of monopoles and their condensation in the QCD ground state is a feature which is related to abelian gauge fixing, discussed in this chapter. The gluon field acquires a singularity in the vicinity of points in space where abelian gauge fixing fails and magnetic monopoles are formed there. The ideas ...
The standard model of low energy (approximately < 10/sup 14/ GeV) physics is based on the groups SU(3) x SU(2) x U(1), a combination of Quantum Chromodynamics and the Glashow-Weinberg-Salam model of the weak interaction. These theories are both non-Abelian gauge theories. A test of one key component of these ...
A general method for determining the target-space symmetries, both broken and unbroken, of string theory is presented. Symmetries are shown to be consequences of a class of automorphisms of the world-sheet operator algebra. This formalism is used to prove general coordinate invariance, two-form gauge invariance, and non-Abelian ...
A model of confined quarks is presented. It involves an abelian (or nonabelian) gauge field coupled to a quark field. The theory is quantized on a discrete space-time lattice. It shows quark confinement for strong coupling. Specifically, for strong coupling isolated quarks have infinite mass and quark- antiquark pairs with a ...

As a step towards an understanding of the infrared structure of non-Abelian gauge theories, we have calculated the anomalous magnetic moment of a colored quark up to fourth-order in the quark-gluon coupling constant g. The fourth-order result is infrared divergent. The infrared divergence is governed by the one loop contribution to the ...
We investigate the microphysics of cosmic strings in non-Abelian gauge theories with N=1 supersymmetry. We give the vortex solutions in a specific example and demonstrate that fermionic superconductivity arises because of the couplings and interactions dictated by supersymmetry. We then use supersymmetry transformations to obtain the ...
We study the quantization of Abelian gauge theories of principal torus bundles over compact manifolds with and without boundary. It is shown that these gauge theories suffer from a Gribov ambiguity originating in the nontriviality of the bundle of connections whose geometrical structure will be ...
The authors consider the implementation of a properly modified form of the Fock-Schwinger gauge condition in a general non-Abelian gauge theory in the context of the BFV formalism. In this paper arguments are presented to justify the necessity of modifying the original Fock-Schwinger condition. The free field ...
I extend the Bloch--Nordsieck idea to show that in the lowest nontrivial order of radiative correction the fermion--fermion and gauge-meson--fermion scattering rates are finite, provided that they are averaged over the initial and summed over the final internal spin states. Questions of the physical gauge coupling and infrared slavery are ...

We study a simple extension of the minimal supersymmetric standard model in which the Abelian sector of the theory consists of B-L and right-handed isospin. In the minimal model this Abelian gauge structure is broken to the standard model hypercharge gauge group by nonvanishing vacuum ...
The partition function of all classical spin models, including all discrete standard statistical models and all Abelian discrete lattice gauge theories (LGTs), is expressed as a special instance of the partition function of the 4D Z2 LGT. This unifies all classical spin models with apparently very different features in a single ...

We study static spherically symmetric solutions of non-Abelian gauge theory coupled to conformal gravity. We find solutions for the self-gravitating pure Yang-Mills case as well as monopolelike solutions of the Higgs system. The former are localized enough to have finite mass and approach asymptotically the vacuum geometry of conformal ...

Non-Abelian gauge symmetry in (3 + 1)-dimensional space-time is analyzed in the causal Epstein-Glaser framework. In this formalism, the technical details concerning the well-known UV and IR problem in quantum field theory are separated and reduced to well-defined problems, namely the causal splitting and the adiabatic switching of ...
We develop an operator formalism for investigating the properties of non-abelian cosmic strings (and vortices) in quantum field theory. Operators are constructed that introduce classical string sources and that create dynamical string loops. The operator construction in lattice gauge theory is explicitly described, ...
Faddeev and Niemi (FN) have introduced an abelian gauge theory which simulates dynamical abelianization in Yang-Mills theory (YM). It contains both YM instantons and Wu-Yang monopoles and appears to be able to describe the confining phase. Motivated by the meson degeneracy problem in dynamical ...
We develop the background field method in the mathcal{N} = 2 , d = 3 superspace for studying effective actions in three-dimensional SYM models which live in the world-volume of various 2-branes. In particular, the low-energy effective action for the mathcal{N} = 2 quiver gauge theory with four chiral superfields in the bifundamental representation is ...
We point out that the Rashba and Dresselhaus spin-orbit interactions in two dimensions can be regarded as a Yang-Mills non-Abelian gauge field. The physical field generated by the gauge field gives the electron wave function a spin-dependent phase which is frequently called the Aharonov-Casher phase. Applying on an AB ring this ...
