A systematization for one-loop 4D Feynman Integrals-different species of massive fields
(Scientific Research, 2019)
A QQ → QQ planar double box in canonical form
(Elsevier Science, 2018-02)
We consider a planar double box with four massive external momenta and two massive internal propagators. We derive the system of differential equations for the relevant master integrals, cast it in canonical form, write ...
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 ...

Field-theory Two-point Functions via Negative Dimension Integration
(Korean Physical Soc, 2012-03-01)
One-loop two-point functions play an important role in quantum field theories, being one of the primary divergent Feynman graphs that calls for regularization and renormalization procedures. These well-known functions are ...

Feynman integrals with tensorial structure in the negative dimensional integration scheme
(1999-12-01)
The negative-dimensional integration method (NDIM) is revealing itself as a very useful technique for computing massless and/or massive Feynman integrals, covariant and noncovanant alike. Up until now however, the illustrative ...

Fun with higher-loop Feynman diagrams
(2016)
We review recent progress that we have achieved in evaluating the class of fully massive vacuum integrals at five loops. After discussing topics that arise in classification, evaluation and algorithmic codification of this ...
