NDIM achievements: massive, arbitrary tensor rank and N-loop insertions in Feynman integrals
(Iop Publishing Ltd, 2000-05-19)
One of the main difficulties in studying quantum field theory, in the perturbative regime, is the calculation of D-dimensional Feynman integrals. In general, one introduces the so-called Feynman parameters and, associated ...

Método de integração em dimensão negativa em teoria quântica de campos
(Universidade Estadual Paulista (Unesp), 2009-05-22)
This work is a review of the Negative Dimension Integration Method as a powerful tool for the computation of the radiative corrections present in Quantum Field Perturbation Theory. This method is applicable in the context ...
Modular application of an integration by fractional expansion method to multiloop Feynman diagrams
(AMER PHYSICAL SOC, 2008)
We present an alternative technique for evaluating multiloop Feynman diagrams, using the integration by fractional expansion method. Here we consider generic diagrams that contain propagators with radiative corrections ...
The double slit experience with light from the point of view of Feynman's sum of multiple pathsO experimento da dupla fenda com luz do ponto de vista da soma de múltiplos caminhos de Feynman
(Soc Brasileira Fisica, 2014-05)
This paper presents an analysis of the double slit experience with light, by using concepts of the Feynman method of “sum of multiple paths” in quantum mechanics. The advantages of this formulation for the teaching of basic ...
