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…
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…
Theory for the FCC-ee : Report on the 11th FCC-ee Workshop
A. Blondel, J. Gluza, S. Jadach +83
The Future Circular Collider (FCC) at CERN, a proposed 100-km circular facility with several colliders in succession, culminates with a 100 TeV proton-proton collider. It offers a…
Causality, unitarity thresholds, anomalous thresholds and infrared singularities from the loop-tree duality at higher orders
J. Jesús Aguilera-Verdugo, Félix Driencourt-Mangin, Judith Plenter +5
We present the first comprehensive analysis of the unitarity thresholds and anomalous thresholds of scattering amplitudes at two loops and beyond based on the loop-tree duality, an…
