A stroll through the loop-tree duality
Jesús Aguilera-Verdugo, Félix Driencourt-Mangin, Roger J. Hernández-Pinto +8
The Loop-Tree Duality (LTD) theorem is an innovative technique to deal with multi-loop scattering amplitudes, leading to integrand-level representations over an Euclidean space. In…
May the four be with you: Novel IR-subtraction methods to tackle NNLO calculations
W. J. Torres Bobadilla, G. F. R. Sborlini, P. Banerjee +21
In this report, we present a discussion about different frameworks to perform precise higher-order computations for high-energy physics. These approaches implement novel strategies…
Mathematical properties of nested residues and their application to multi-loop scattering amplitudes
J. Jesus Aguilera-Verdugo, Roger J. Hernandez-Pinto, German Rodrigo +2
The computation of multi-loop multi-leg scattering amplitudes plays a key role to improve the precision of theoretical predictions for particle physics at high-energy colliders. In…
Open loop amplitudes and causality to all orders and powers from the loop-tree duality
J. Jesus Aguilera-Verdugo, Felix Driencourt-Mangin, Roger J. Hernandez-Pinto +7
Multiloop scattering amplitudes describing the quantum fluctuations at high-energy scattering processes are the main bottleneck in perturbative quantum field theory. The loop-tree…
Recent developments from the loop-tree duality
German Rodrigo, Felix Driencourt-Mangin, German F. R. Sborlini +1
In this talk, we review the most recent developments of the four-dimensional unsubstraction (FDU) and loop-tree duality (LTD) methods. In particular, we make emphasis on the advant…
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…
