Non-abelian field cohomology, its relation with spontaneous symmetry breaking and Morse's Theorem
V. E. R. Lemes
We show that, for an gauge field (the reasoning extends trivially to ), spontaneous symmetry breaking changes the field cohomology. This defines a new field with coh…
Gauge invariant nonlocal mass operator in YM theories
D. Dudal, N. Vandersickel, H. Verschelde +5
We briefly describe the construction of a renormalizable gauge model based on the nonlocal gauge invariant mass operator F1/D^2F. We also take a look at the unitarity of the result…
On The Complete Seiberg-Witten Map For Theories With Topological Terms
L. C. Q. Vilar, O. S. Ventura, R. L. P. G. Amaral +2
The SW map problem is formulated and solved in the BRST cohomological approach. The well known ambiguities of the SW map are shown to be associated to distinct cohomological classe…
Remarks on a class of renormalizable interpolating gauges
D. Dudal, J. A. Gracey, V. E. R. Lemes +4
A class of covariant gauges allowing one to interpolate between the Landau, the maximal Abelian, the linear covariant and the Curci-Ferrari gauges is discussed. Multiplicative reno…
Off-diagonal mass generation for Yang-Mills theories in the maximal Abelian gauge
D. Dudal, J. A. Gracey, V. E. R. Lemes +4
We investigate a dynamical mass generation mechanism for the off-diagonal gluons and ghosts in SU(N) Yang-Mills theories, quantized in the maximal Abelian gauge. Such a mass can be…
Vacuum Condensates and Dynamical Mass Generation in Euclidean Yang-Mills Theories
D. Dudal, H. Verschelde, V. E. R. Lemes +6
Vacuum condensates of dimension two and their relevance for the dynamical mass generation for gluons in Yang-Mills theories are discussed
