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…
The 1/N Expansion in Noncommutative Quantum Mechanics
A. F. Ferrari, M. Gomes, C. A. Stechhahn
We study the 1/N expansion in noncommutative quantum mechanics for the anharmonic and Coulombian potentials. The expansion for the anharmonic oscillator presented good convergence…
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…
