Bumblebee field in a Topological Framework
L. P. Colatto, A. L. A. Penna, W. C. Santos
A vector field coming from spontaneous Lorentz violation mechanism, namely Bumblebee model is analysed in a topological framework in a Minkowski space-time. Taking a $(1+2…
A chargeless complex vector matter field in supersymmetric scenario
L. P. Colatto, A. L. A. Penna
In this paper we construct and study a formulation of a chargeless complex vector matter field in a supersymmetric framework. To this aim we combine two no-chiral scalar superfield…
Mass Generation and Related Issues from Exotic Higher Dimensions
M. Rojas, M. A. De Andrade, L. P. Colatto +3
The main purpose of this work is to show that massless Dirac equation formulated for non-interacting Majorana-Weyl spinors in higher dimensions, particularly in D=1+9 and D=5+5, ca…
Magnetic Moment Generation from non-minimal couplings in a scenario with Lorentz-Symmetry Violation
H. Belich, L. P. Colatto, T. Costa-Soares +2
This paper deals with situations that illustrate how the violation of Lorentz symmetry in the gauge sector may contribute to magnetic moment generation of massive neutral particles…
Noncommutative geometry induced by spin effects
L. P. Colatto, A. L. A. Penna, W. C. Santos
In this paper we study the nonlocal effects of noncommutative spacetime on simple physical systems. Our main point is the assumption that the noncommutative effects are consequence…
Remarks on some vacuum solutions of scalar-tensor cosmological models
V. B. Bezerra, C. Romero, G. Grebot +2
We present a class of exact vacuum solutions corresponding to de Sitter and warm inflation models in the framework of scalar-tensor cosmologies. We show that in both cases the fiel…
