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…
Differential Space of Feynman Integrals: Annihilators and -module
Vsevolod Chestnov, Wojciech Flieger, Pierpaolo Mastrolia +3
We present a novel algorithm for constructing differential operators with respect to external variables that annihilate Feynman-like integrals and give rise to the associated $\mat…
Two-loop Feynman integrals for leading colour production at hadron colliders
Matteo Becchetti, Dhimiter Canko, Vsevolod Chestnov +3
We compute a complete set of the two-loop Feynman integrals that are required for the next-to-next-to-leading order QCD corrections to on-shell top-pair production in association w…
