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…
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…
On the interplay between the loop-tree duality and helicity amplitudes
Felix Driencourt-Mangin, German Rodrigo, German F. R. Sborlini +1
The spinor-helicity formalism has proven to be very efficient in the calculation of scattering amplitudes in quantum field theory, while the loop tree duality (LTD) representation…

Felix Driencourt-Mangin
In this thesis we propose a novel method to compute higher-order corrections to physical cross sections, bypassing more traditional approaches. This technique, the Four-Dimensional…
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…

We extend useful properties of the unintegrated dual amplitudes from one- to two-loop level, using the Loop-Tree Duality formalism. In particular, we show that the univers…
Les Houches 2017: Physics at TeV Colliders Standard Model Working Group Report
J. Bendavid, F. Caola, V. Ciulli +102
This Report summarizes the proceedings of the 2017 Les Houches workshop on Physics at TeV Colliders. Session 1 dealt with (I) new developments relevant for high precision Standard…
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…

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…
