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…
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…
One-loop amplitudes for and productions at the LHC through
Souvik Bera, Colomba Brancaccio, Dhimiter Canko +1
We present analytic expressions for the one-loop QCD helicity amplitudes contributing to top-quark pair production in association with a photon or a jet at the Large Hadron Collide…
All planar three-loop Feynman integrals for the production of two vector bosons at hadron colliders
Dhimiter Canko, Mattia Pozzoli
We compute all the planar three-loop master integrals relevant for the leading colour N3LO QCD corrections to the production of two massive or off-shell vector bosons at hadron col…
Towards numerical two-loop integrand reduction
Giuseppe Bevilacqua, Dhimiter Canko, Costas Papadopoulos +1
We present a method for the integrand-level reduction of two-loop helicity amplitudes in both and dimensions. The amplitude is expressed in terms of a set of Feynma…
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…
