Charge and Spin Currents in a Lower-Dimensional Supersymmetric Model in Presence of Vortices
Cristine N. Ferreira, J. P. S. Alves e Silva, J. A. Helayel Neto +1
We investigate charge and spin currents that may appear in some materials, considering the possible couplings and the symmetries of a field-theoretical model presented here. We ins…
A Discussion on Possible Effects of the Barbero-Immirzi Parameter at the TeV-scale Particle Physics
Nelson Panza, Hilário Rodrigues, Denis Cocuroci +1
In this paper, we analyse a curvature- and torsion-square quantum gravity action with an additional Holst term minimally coupled to a massive Dirac field in four dimensions. The ma…
Discussing the Spectrum of the Kalb-Ramond Field Coupled to 3D-Gravity
J. L. Boldo, J. A. Helayel-Neto, N. Panza
The mechanism of dynamical mass generation for the gauge field is studied through 1-loop. We find out that torsion is an obstruction to the appearance of a 1-loop mass correction.…
Propagating Torsion in 3D-Gravity and Dynamical Mass Generation
J. L. Boldo, J. A. Helayel-Neto, N. Panza
In this paper, fermions are minimally coupled to 3D-gravity where a dynamical torsion is introduced. A Kalb-Ramond field is non-minimally coupled to these fermions in a gauge-invar…
On Massive Vector Bosons and Abelian Magnetic Monopoles in D=(3+1): a Possible Way to Quantise the Topological Mass Parameter
Winder A. Moura-Melo, N. Panza, J. A. Helayel-Neto
An Abelian gauge model, with vector and 2-form potential fields linked by a topological mass term that mixes the two Abelian factors, is shown to exhibit Dirac-like magnetic monopo…
