Tensor decomposition of to higher orders in the dimensional regulator
Thomas Dave, Jérémy Paltrinieri, Pau Petit Rosàs +1
We present a first study of the scattering process beyond next-to-leading order, aimed at providing preliminary insights required for future NNLO predictions fo…
Six-loop gravitational interactions at the sixth post-Newtonian order
Giacomo Brunello, Manoj K. Mandal, Pierpaolo Mastrolia +6
We compute the gravitational interaction of two coalescing compact objects at sixth post-Newtonian order in the static limit, employing the diagrammatic approach within the effecti…

G. Abbiendi, A. Arbuzov, Sw. Banerjee +31
The mini-proceedings of the STRONG2020 Virtual Workshop "Space-like and Time-like determination of the Hadronic Leading Order contribution to the Muon ", November 24--26 2021,…
Causal representation and numerical evaluation of multi-loop Feynman integrals
William J. Torres Bobadilla
The loop-tree duality (LTD) has become a novelty alternative to bootstrap the numerical evaluation of multi-loop scattering amplitudes. It has indeed been found that Feynman integr…
Four-loop scattering amplitudes journey into the forest
Selomit Ramírez-Uribe, Roger J. Hernández-Pinto, Andrés E. Rentería-Olivo +4
We present an overview of the analysis of the multiloop topologies that appear for the first time at four loops and the assembly of them in a general expression, the NMLT unive…
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…
Lotty -- The loop-tree duality automation
William J. Torres Bobadilla
Elaborating on the novel formulation of the loop-tree duality, we introduce the Mathematica package Lotty that automates the latter at multi-loop level. By studying the features of…

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…

P. Banerjee, C. M. Carloni Calame, M. Chiesa +17
We review the current status of the theory predictions for elastic - scattering, describing the recent activities and future plans of the theory initiative related to the pro…
Calculating the static gravitational two-body potential to fifth post-Newtonian order with Feynman diagrams
Stefano Foffa, Pierpaolo Mastrolia, Riccardo Sturani +2
We discuss the first-time calculation of the static gravitational two-body potential up to fifth post-Newtonian(PN) order. The results are achieved through a manifest factorization…
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…
