Nonabelian Topological Mass Generation in 4 Dimensions
نویسندگان
چکیده
We study the topological mass generation in the 4 dimensional nonabelian gauge theory, which is the extension of the Allen et al.’s work in the abelian theory. It is crucial to introduce a one form auxiliary field in constructing the gauge invariant nonabelian action which contains both the one form vector gauge field A and the two form antisymmetric tensor field B. As in the abelian case, the topological coupling mB ∧ F , where F is the field strength of A, makes the transmutation among A and B possible, and consequently we see that the gauge field becomes massive. We find the BRST/anti-BRST transformation rule using the horizontality condition, and construct a BRST/anti-BRST invariant quantum action. PACS codes: 11.10.-z, 11.15.-q, 12.90.+b

A No-Go Theorem for the Nonabelian Topological Mass Mechanism in Four Dimensions
We prove that there is no power-counting renormalizable nonabelian generalization of the abelian topological mass mechanism in four dimensions. The argument is based on the technique of consistent deformations of the master equation developed by G. Barnich and one of the authors. Recent attempts involving extra fields are also commented upon.
متن کاملMagnetic Wormholes and Topological Symmetry*
We investigate the wormhole solutions that arise in the semiclassical analysis of euclidean gravity coupled to gauge fields. In 2 + 1 dimensions, "magnetic monopole" solutions can be constructed, for either abelian or nonabelian gauge fields. The low-energy physics induced by these wormholes qualitatively resembles, but is quantitatively distinguishable from, the tow-energy physics of a gauge t...
متن کاملTopological mass generation in four dimensions.
We show that in a large class of physically interesting systems the mass-generation phenomenon can be understood in terms of topological structures, without requiring a detailed knowledge of the underlying dynamics. This is first demonstrated by showing that Schwinger's mechanism for mass generation relies on topological structures of a two-dimensional gauge theory. In the same manner, correspo...

Vacuum effects in (2+1)-dimensional quantum electrodynamics (QED) with the topological Chern-Simons term are considered. The photon polarization operator is studied and the decay rate for the electron-positron photoproduction γ → e+ e− is presented as a function of the photon energy and external field strength. The radiatively induced electron mass shift in an external magnetic field is investi...
