Path Integral Quantization of Generalized Stueckelberg Electrodynamics: A Faddeev-Jackiw Approach
L. G. Caro, G. B. de Gracia, A. A. Nogueira +1
We build a setup for path integral quantization through the Faddeev-Jackiw approach, extending it to include Grassmannian degrees of freedom, to be later implemented in a model of…
Fermionic dark matter-photon quantum interaction: A mechanism for darkness
G. B. de Gracia, A. A. Nogueira, R. da Rocha
Mass dimension one fermionic fields are prime candidates to describe dark matter, due to their intrinsic neutral nature, as they are constructed as eigenstates of the charge conjug…
Spontaneous symmetry breakings in the singlet scalar Yukawa model within the auxiliary field method
A. A. Nogueira, F. L. Braghin
The aim of this work is to investigate the occurrence of two different spontaneous symmetry breakings {at} two levels of the description of fermion-scalar field model, by means of…
Dirichlet boundary condition for the Lee-Wick-like scalar model
L. H. C. Borges, A. A. Nogueira, E. H. Rodrigues +1
Lee-Wick-like scalar model near a Dirichlet plate is considered in this work. The modified propagator for the scalar field due to the presence of a Dirichlet boundary is computed,…
A Generalized Stueckelberg-Higgs gauge theories
C. A. Bonin, G. B. de Gracia, A. A. Nogueira +1
The aim of this work is to discuss and explore some generalized aspects of generation of photon mass respecting gauge symmetry. We introduce generalized Stueckelberg and Higgs gaug…
Higgs Mechanism and Debye Screening in the Generalized Electrodynamics
C. A. Bonin, G. B. de Gracia, A. A. Nogueira +1
In this work we study the Higgs mechanism and the Debye shielding for the Bopp-Podolsky theory of electrodynamics. We find that not only the massless sector of the Podolsky theory…
Transition amplitude, partition function and the role of physical degrees of freedom in gauge theories
A. A. Nogueira, B. M. Pimentel, L. Rabanal
This work explores the quantum dynamics of the interaction between scalar (matter) and vectorial (intermediate) particles and studies their thermodynamic equilibrium in the grand-c…
Reduction of order and Fadeev-Jackiw formalism in generalized electrodynamics
A. A. Nogueira, C. Palechor, A. F. Ferrari
The aim of this work is to discuss some aspects of the reduction of order formalism in the context of the Fadeev-Jackiw symplectic formalism, both at the classical and the quantum…
Radiative Corrections in GSDKP
R. Bufalo, T. R. Cardoso, A. A. Nogueira +1
We show explicit the first radiative correction for the vertex and photon-photon 4-point function in Generalized Scalar Duffin-Kemmer-Petiau Quantum Electrodynamcis (GSDKP), utiliz…
BRST symmetry and fictitious parameters
A. A. Nogueira, B. M. Pimentel
Our goal in this work is to present the variational method of fictitious parameters and its connection with the BRST symmetry. Firstly we implement the method in QED at zero temper…
Functional quantization of Generalized Scalar Duffin-Kemmer-Petiau Electrodynamics
R. Bufalo, T. R. Cardoso, A. A. Nogueira +1
The main goal of this work is to study systematically the quantum aspects of the interaction between scalar particles in the framework of Generalized Scalar Duffin-Kemmer-Petiau El…
A Conducting surface in Lee-Wick electrodynamics
F. A. Barone, A. A Nogueira
The Lee-Wick electrodynamics in the vicinity of a conducting plate is investigated. The propagator for the gauge field is calculated and the interaction between the plate and a poi…
External Sources in Lee-Wick Theories
F. A. Barone, G. Flores-Hidalgo, A. A Nogueira
We investigate some peculiar aspects of the so called Lee-Wick Electrodynamics focusing on physical effects produced by the presence of sources for the vector field. The interactio…
