Restoring the gauge invariance in non-Abelian second-class theories
Paulo R. F. Alves, Cleber N. Costa, D. Fiorentini +3
In this paper, we propose a generalization of an improved gauge unfixing formalism in order to generate gauge symmetries in the non-Abelian valued systems. This generalization disp…
Gauge theories and gravity
R. F. Sobreiro, A. A. Tomaz, V. J. Vasquez Otoya
Pure gauge theories for de Sitter, anti de Sitter and orthogonal groups, in four-dimensional Euclidean spacetime, are studied. It is shown that, if the theory is asymptotically fre…
Formal aspects of spin currents in material media
T. R. S. Santos, R. F. Sobreiro, V. J. Vasquez Otoya
The relativistic generalization of the broken continuity equation that describes spin currents is exploited in general material media. The field theoretical techniques for the usua…
Aspects of nonmetricity in gravity theories
R. F. Sobreiro, V. J. Vasquez Otoya
In this work, we show that a class of metric-affine gravities can be reduced to a Riemann-Cartan one. The reduction is based on the cancelation of the nonmetricity against the symm…
Effective gravity from a quantum gauge theory in Euclidean space-time
R. F. Sobreiro, V. J. Vasquez Otoya
We consider a gauge theory in an Euclidean -dimensional space-time, which is known to be renormalizable to all orders in perturbation theory for . Then, wit…
Remarks on Quantum Aspects of 3D-Gravity in the First-Order Formalism
L M de Moraes, J A Helayel-Neto, V J Vasquez Otoya
In this paper, we reassess the issue of working out the propagators and identifying the spectrum of excitations associated to the vielbein and spin connection of (1+2)-D gravity in…
