Thinking anew causality problems for the radiation reaction force
Reinaldo de Melo e Souza, J. A. Helayël Neto
In this work, we analyze a Lagrangian formalism recently proposed to approach the issue of the Abraham-Lorentz force. Instead of involving only position and velocity, as usual in C…
Supersymmetric generalization of the maximal Abelian gauge
M. A. L. Capri, H. C. Toledo, J. A. Helayël-Neto
We present an N=1 supersymmetric generalization of the Maximal Abelian Gauge (MAG) in its superfield and component-field formulations, and discuss its Faddeev-Popov quantization, t…
Supergraph Approach in a Higher-order LDE Calculation of the Effective Potential for F-type Broken SUSY
M. C. B. Abdalla, R. L. S. Farias, J. A. Helayël-Neto +2
In this work, we adopt the simplest model that spontaneously breaks supersymmetry, namely, the minimal O'Raifeartaigh model. The effective potential is computed in the framework of…
N=1-Supersymmetric Description of a Spin-1/2 charged Particle in a 5d-World
H. Belich, D. Cocuroci, G. S. Dias +2
We study the dynamics of a charged spin-1/2 particle in an external 5-dimensional electromagnetic field. We then consider that we are at the \ scale, so that we can access the…
Superspace approach to the renormalization of the O'Raifeartaigh model up to the second order in the LDE parameter
M. C. B. Abdalla, J. A. Helayël-Neto, Daniel L. Nedel +1
We adopt a superspace/supergraph formalism to pursue the investigation of the structure of one- and two-loop divergences in the frame of the minimal O'Raifeartaigh model that reali…
On the Potentials of Supersymmetric Theories with Gauge-Field Mixing Terms
Cristine N. Ferreira, Helder Chavez, Jose A. Helayel-Neto
In this letter, we reconsider the delicate issue of symmetry and supersymmetry breakings for gauge theories with gauge-field mixings. The purpose is to study generalyzed potentials…
