From Jacobi off-shell currents to integral relations
Jose Llanes Jurado, German Rodrigo, William J. Torres Bobadilla
In this paper, we study off-shell currents built from the Jacobi identity of the kinematic numerators of with . We find that these currents can be schem…
Four-dimensional regularization of higher-order computations: FDU approach
German F. R. Sborlini, Felix Driencourt-Mangin, Roger Hernandez-Pinto +1
We have recently proposed a new regularization framework based on the loop-tree duality theorem. This theorem allows to rewrite loop level amplitudes in terms of tree-level structu…
QED and QCD self-energy corrections through the loop-tree duality
N. Selomit Ramírez-Uribe, Roger J. Hernández-Pinto, Germán Rodrigo
The loop-tree duality (LTD) theorem establishes that loop contributions to scattering amplitudes can be computed through dual integrals, which are build from single cuts of the vir…
On the universal structure of Higgs amplitudes mediated by heavy particles
German F. R. Sborlini, Felix Driencourt-Mangin, German Rodrigo
We describe the calculation of the one-loop corrections to and within the four-dimensional unsubtraction/loop-tree duality (FDU/LTD) approach. The fact that…
To , or not to : Recent developments and comparisons of regularization schemes
C. Gnendiger, A. Signer, D. Stöckinger +16
We give an introduction to several regularization schemes that deal with ultraviolet and infrared singularities appearing in higher-order computations in quantum field theories. Co…
Universal dual amplitudes and asymptotic expansions for and in four dimensions
Felix Driencourt-Mangin, German Rodrigo, German F. R. Sborlini
Though the one-loop amplitudes of the Higgs boson to massless gauge bosons are finite because there is no direct interaction at tree-level in the Standard Model, a well-defined reg…
