We investigate the single off-shell scalar box integral with massless internal lines in dimensional regularization. A special emphasis is given to higher orders in the dimensional regularization ...
ABSTRACT: A systematization for the manipulations and calculations involving divergent (or not) Feynman integrals, typical of the one loop perturbative solutions of Quantum Field Theory, is proposed.

A simple expression for the four-point scalar function from Gaussian integrals and Fourier transform
Recasting the N N N-point one loop scalar integral from Feynman to Schwinger parameters gives an integrand with a Gaussian form. By application of a Fourier transform, it is easy to derive explicit ...
Abstract: We introduce new vector diffractive integrals, which can be used for the radio holographic remote sensing of the atmosphere and terrestrial surfaces. These integrals are exact relationships ...
Abstract: Magnetic field problems can be accurately solved with the integral equation method in combination with a total scalar potential approach. However, only nonhysteretic magnetic material has ...
