Revisiting the two-body problem in Yukawa gravity and in a gravitational extension of the Buckingham potential
E. A. Gallegos, R. Perca Gonzales, J. F. Jesus
We revisit the Keplerian-like parametrization of the two-body problem in Yukawa gravity studied in the literature. Some inconsistencies, which spoil Bertrand's theorem, observed in…
Lifshitz-Wess-Zumino model: A paradigm of reconciliation between Lifshitz-like operators and supersymmetry
E. A. Gallegos
By imposing the weighted renormalization condition and the (super)symmetry requirements, we construct a Lifshitz-like extension of the three-dimensional Wess-Zumino model, with dyn…
Two-loop finiteness of self-energies in higher-derivative SQED3
E. A. Gallegos, R. Baptista
In the superfield formalism, two higher-derivative kinetic operators (Lee-Wick operators) are implemented into the standard three dimensional supersymmetric quantum electrodynamics…
Some Generalizations in Supersymmetric Quantum Mechanics and the Supersymmetric -System Revisited
E. A. Gallegos, A. J. da Silva, D. Spehler
We discuss two distinct aspects in supersymmetric quantum mechanics. First, we introduce a new class of operators A and in terms of anticommutators between the momentum o…
Higher-Derivative Wess-Zumino Model in Three Dimensions
E. A. Gallegos, C. R. Senise, A. J. da Silva
We deform the well-known three dimensional Wess-Zumino model by adding higher derivative operators (Lee-Wick operators) to its action. The effects of these operator…
Dynamical (super)symmetry vacuum properties of the supersymmetric Chern-Simons-matter model
E. A. Gallegos, A. J. da Silva
By computing the two-loop effective potential of the D=3 N=1 supersymmetric Chern-Simons model minimally coupled to a massless self-interacting matter superfield, it is shown that…
Supergraph techniques for D=3,N=1 broken supersymmetric theories
E. A. Gallegos, A. J. da Silva
We enlarge the usual D=3 N=1 supergraph techniques to include the case of (explicitly or spontaneously) broken supersymmetric gauge theories. To illustrate the utility of these tec…
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…
