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…
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…
Non-perturbative aspects of Yang-Mills theories
R. F. Sobreiro
Some nonperturbative aspects of Euclidean Yang-Mills theories in four dimensions, quantized in the Landau gauge, are analytically studied. In particular, we investigate the dynamic…
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…
Local renormalizable gauge theories from nonlocal operators
M. A. L. Capri, V. E. R. Lemes, R. F. Sobreiro +2
The possibility that nonlocal operators might be added to the Yang-Mills action is investigated. We point out that there exists a class of nonlocal operators which lead to renormal…
