Electron and muon anomalous magnetic dipole moment in a 3-3-1 model
(Springer, 2017-05-19)
We calculate, in the context of a 3-3-1 model with heavy charged leptons, constraints on some parameters of the extra particles in the model by imposing that their contributions to both the electron and muon (g - 2) factors ...
On the structure of physical space

O(N) model in Euclidean de Sitter space: beyond the leading infrared approximation
(Springer, 2016-09-19)
We consider an O(N) scalar field model with quartic interaction in d-dimensional Euclidean de Sitter space. In order to avoid the problems of the standard perturbative calculations for light and massless fields, we generalize ...
Dissipative effects in the effective field theory of inflation
(Springer, 2012-01)
We generalize the effective field theory of single clock inflation to include dissipative effects. Working in unitary gauge we couple a set of composite operators, Oµν..., in the effective action which is constrained solely ...
The Dirac-Hestenes equation for spherical symmetric potentials in the spherical and Cartesian gauges
(2006-08-10)
In this paper, using the apparatus of the Clifford bundle formalism, we show how straightforwardly solve in Minkowski space-time the Dirac-Hestenes equation - which is an appropriate representative in the Clifford bundle ...

Scattering and bound states of fermions in a mixed vector-scalar smooth step potential
(Elsevier B.V., 2014-07-01)
The scattering of a fermion in the background of a smooth step potential is considered with a general mixing of vector and scalar Lorentz structures with the scalar coupling stronger than or equal to the vector coupling. ...
Loop quantization of the Gowdy model with local rotational symmetry
(AMER PHYSICAL SOC, 2017)
We provide a full quantization of the vacuum Gowdy model with local rotational symmetry. We consider a redefinition of the constraints where the Hamiltonian Poisson-commutes with itself. We then apply the canonical ...
Long distance behavior of O(N)-model correlators in de Sitter space and the resummation of secular terms
(Springer, 2018-10)
We analyze the long distance behavior of the two-point functions for an interacting scalar O(N) model in de Sitter spacetime. Following our previous work, this behavior is analyzed by analytic continuation of the Euclidean ...
