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…
Universal opening of four-loop scattering amplitudes to trees
Selomit Ramirez-Uribe, Roger J. Hernandez-Pinto, German Rodrigo +2
The perturbative approach to quantum field theories has made it possible to obtain incredibly accurate theoretical predictions in high-energy physics. Although various techniques h…
Causal representation of multi-loop Feynman integrands within the loop-tree duality
J. Jesus Aguilera-Verdugo, Roger J. Hernandez-Pinto, German Rodrigo +2
The numerical evaluation of multi-loop scattering amplitudes in the Feynman representation usually requires to deal with both physical (causal) and unphysical (non-causal) singular…
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…
