Symmetry Origin of Infrared Divergence Cancellation in Topologically Massive Yang-Mills Theory
نویسنده
چکیده
We manifestly verify that the miraculous cancellation of the infrared divergence of the topologically massive Yang-Mills theory in the Landau gauge is completely determined by a new vector symmetry existing in its large topological mass limit, the Chern-Simons theory. Furthermore, we show that the cancellation theorem proposed by Pisarski and Rao is an inevitable consequence of this new vector symmetry. PACS: 11.10.Kk, 11.15.-q, 03.70.tk

Perturbative analysis on infrared and ultraviolet aspects of noncommutative QED on R
Here we discuss the ultraviolet and infrared aspects of the noncommutative counterpart of QED, which is called as noncommutative QED, as well as some infrared dynamics of noncommutative Yang-Mills (NCYM) theory. First we demonstrate that the divergence in the theory can be subtracted by the similar counterterms as in ordinary theory at one loop level. Then the anomalous magnetic moment is calcu...
متن کاملDifferential regularization of topologically massive Yang-Mills theory and Chern-Simons theory
We apply a differential renormalization method to the study of three-dimensional topologically massive Yang-Mills and Chern-Simons theories. The method is especially suitable for such theories as it avoids the need for dimensional continuation of a three-dimensional antisymmetric tensor and the Feynman rules for three-dimensional theories in coordinate space are relatively simple. The calculus ...
متن کاملPerturbative analysis on infrared aspects of noncommutative QED on R
Here we examine the noncommutative counterpart of QED, which is called as noncommutative QED. The theory is obtained by examining the consistent minimal coupling to noncommutative U(1) gauge field. The ∗-product admits the coupling of the matter with only three varieties of charges, i.e., 0, +1 and −1. Ultraviolet divergence can be absorbed into the rescaling of the fields and the parameters at...
متن کاملGroup approach to quantization of Yang–Mills theories: a cohomological origin of mass
New clues for the best understanding of the nature of the symmetry-breaking mechanism are revealed in this paper. A revision of the standard gauge transformation properties of Yang–Mills fields, according to a group approach to the quantization scheme, enables the gauge group coordinates to acquire dynamical content outside the null mass shell. The corresponding extra (internal) field degrees o...
متن کاملAsymptotically Free Yang-Mills Classical Mechanics with Self-Linked Orbits
We construct a classical mechanics Hamiltonian which exhibits spontaneous symmetry breaking akin the Coleman-Weinberg mechanism, dimensional transmutation, and asymptotically free self-similarity congruent with the beta-function of four dimensional Yang-Mills theory. Its classical equations of motion support stable periodic orbits and in a three dimensional projection these orbits are self-link...
