Field-theory Two-point Functions via Negative Dimension Integration
(Korean Physical Soc, 2014)
Non-planar double-box, massive and massless pentabox Feynman integrals in the negative-dimensional approach
(Iop Publishing Ltd, 2002-01-11)
The negative-dimensional integration method is a technique which can be applied, with success, in usual covariant gauge calculations. We consider three two-loop diagrams: the scalar massless non-planar double-box with six ...

Massless and massive one-loop three-point functions in negative dimensional approach
(Springer, 2002-11-01)
In this article we present the complete massless and massive one-loop triangle diagram results using the negative dimensional integration method (NDIM). We consider the following cases: massless internal fields; one massive, ...

Aspectos dimensionais da massa do fóton na eletrodinâmica quântica
(Universidade Federal de Santa MariaCentro de Ciências Naturais e Exatas, 2014-12-10)
The gauge invariance of Quantum Electrodynamics establishes a non massive character for the photon field. Nevertheless, corrections at one loop level for the self-energy of the photon can induce mass generation in some ...
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 ...
