Spontaneous breaking of superconformal invariance in (2+1)D supersymmetric Chern-Simons-matter theories in the large N limit
A. C. Lehum, A. J. da Silva
In this work it is studied the spontaneous breaking of superconformal and gauge invariances in the Abelian N=1,2 three-dimensional supersymmetric Chern-Simons-matter theories in a…
Lorentz violation in the linearized gravity
A. F. Ferrari, A. Yu. Petrov
We study some consequences of the introduction of a Lorentz-violating modification term in the linearized gravity, which leads to modified dispersion relations for gravitational wa…
On the aether-like Lorentz-breaking action for the electromagnetic field
M. Gomes, J. R. Nascimento, A. Yu. Petrov +1
We study the generation of aether-like Lorentz-breaking actions in three, four and five dimensions via an appropriate Lorentz-breaking coupling of electromagnetic and spinor fields…
The Slavnov-Taylor Identities for the 2+1 Dimensional Noncommutative CP Model
B. Charneski, M. Gomes, T. Mariz +2
In the context of the expansion, the validity of the Slavnov-Taylor identity relating three and two point functions for the dimensional noncommutative CP model…
Horava-Lifshitz modifications of the Casimir effect
A. F. Ferrari, H. O. Girotti, M. Gomes +2
We study the modifications induced by spacetime anisotropy on the Casimir effect in the case of two parallel plates. Nonperturbative and perturbative regimes are analyzed. In the f…
Coleman-Weinberg mechanism in a three-dimensional supersymmetric Chern-Simons-matter model
A. F. Ferrari, E. A. Gallegos, M. Gomes +4
Using the superfield formalism, we study the dynamical breaking of gauge symmetry in the N=1 three-dimensional supersymmetric Chern-Simons model, coupled to a complex scalar superf…
Noncommutativity due to spin
M. Gomes, V. G. Kupriyanov, A. J. da Silva
Using the Berezin-Marinov pseudoclassical formulation of spin particle we propose a classical model of spin noncommutativity. In the nonrelativistic case, the Poisson brackets betw…
Slavnov-Taylor identities for noncommutative QED
B. Charneski, M. Gomes, T. Mariz +2
In this work we present an analysis of the one-loop Slavnov-Taylor identities in noncommutative QED. The vectorial fermion-photon and the triple photon vertex functions were st…
