Nonlocal four-fermion theory
F. M. Belchior, J. R. Nascimento, A. Yu. Petrov +1
In this work, we formulate and analyze a nonlocal four-fermion theory in which the usual Dirac operator is deformed by an entire nonlocal form factor. After introducing an auxiliar…
Four-dimensional supersymmetric massive QED
A. C. Lehum, J. R. Nascimento, A. Yu. Petrov
We discuss the massive extension of the four-dimensional superfield QED. For this theory, we calculate the one-loop effective potential of the chiral matter.
A novel nonlocal spin-1/2 theory: classical and quantum aspects
J. R. Nascimento, Gonzalo J. Olmo, A. Yu. Petrov +2
We propose a novel nonlocal spin-1/2 theory in which the form factor depends on the Dirac operator rather than on the d'Alembert operator. In this scenario, we explore some classic…
Perturbative aspects of the supersymmetric three-dimensional massive QED
A. C. Lehum, J. R. Nascimento, A. C. Pina Neto +1
We perform the study of perturbative aspects of a three-dimensional supersymmetric Maxwell-Chern-Simons-Proca theory minimally coupled to scalar superfields. Using the superfield f…
Properties of an axisymmetric Lorentzian non-commutative black hole
A. A. Araújo Filho, J. R. Nascimento, A. Yu. Petrov +2
In this work, we start by examining a spherically symmetric black hole within the framework of non-commutative geometry and apply a modified Newman-Janis method to obtain a new rot…
Generalized Chern-Pontryagin models
J. R. Nascimento, A. Yu. Petrov, P. J. Porfírio +1
We formulate a new class of modified gravity models, that is, generalized four-dimensional Chern-Pontryagin models, whose action is characterized by an arbitrary function of the Ri…
