Two-loop QCD amplitudes for production at the LHC in the leading-colour approximation
Matteo Becchetti, Dhimiter Canko, Xiang Chen +7
We present a numerical computation of the two-loop QCD scattering amplitudes for the production of a top-antitop quark pair in association with a boson () at the LHC…
Landau's Leviathans
Vsevolod Chestnov, Giulio Crisanti, Mathieu Giroux
We present a new method together with a proof-of-concept implementation for determining the Landau singularities of Feynman integrals, read off directly from where the Euler charac…
NNLO QCD predictions for production at hadron colliders
Matteo Becchetti, Dhimiter Canko, Xiang Chen +10
The production of a top-antitop quark pair in association with a boson constitutes one of the heaviest final states currently studied at the Large Hadron Collider (LHC) at CERN…
Hexagon Bootstrap in the Double Scaling Limit
Vsevolod Chestnov, Georgios Papathanasiou
We study the six-particle amplitude in planar super Yang-Mills theory in the double scaling (DS) limit, the only nontrivial codimension-one boundary of its positi…
Sampling Polynomial Rational Remainders with SPR: A new Package for Polynomial Division and Elimination
Vsevolod Chestnov, Giulio Crisanti
We introduce SPR, a new Mathematica package for the division and elimination of variables from polynomial systems. SPR works by sampling and reconstructing…
Gravitational waveforms from restriction theory and rapid-decay homology
Giacomo Brunello, Vsevolod Chestnov, Giulio Crisanti +2
We present a systematic framework for computing frequency-domain gravitational waveforms from relativistic binary scattering in different asymptotic regimes. The method yields a co…
