The precision frontier in collider physics is being pushed at impressive speed, from both the
experimental and the theoretical side. The aim of this review is to give an overview of recent …

In this manuscript, we report the outcome of the topical workshop: paving the way to
alternative NNLO strategies (https://indico. ific. uv. es/e/WorkStop-ThinkStart_3. 0), by …

An impressive effort is being pursued in order to develop new strategies that allow an
efficient computation of multi-loop multi-leg Feynman integrals and scattering amplitudes …

A bstract The causal representation of multi-loop scattering amplitudes, obtained from the
application of the loop-tree duality formalism, comprehensively elucidates, at integrand …

A bstract The numerical evaluation of multi-loop scattering amplitudes in the Feynman
representation usually requires to deal with both physical (causal) and unphysical (non …

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 Lotty …

A bstract The perturbative approach to quantum field theories has made it possible to obtain
incredibly accurate theoretical predictions in high-energy physics. Although various …

A bstract We present a novel benchmark application of a quantum algorithm to Feynman
loop integrals. The two on-shell states of a Feynman propagator are identified with the two …

A bstract The Local Unitarity (LU) representation of differential cross-sections locally realises
the cancellations of infrared singularities predicted by the Kinoshita-Lee-Nauenberg …

A bstract We propose a novel local subtraction scheme for the computation of Next-to-
Leading Order contributions to theoretical predictions for scattering processes in …
