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…
Double virtual QCD corrections to jet production at the LHC
Simon Badger, Matteo Becchetti, Colomba Brancaccio +4
We present a leading colour computation of the double virtual contributions to top-quark pair production in association with a jet at a hadron collider at next-to-next-to-leading o…
Higher-order QCD corrections to top-quark pair production in association with a jet
Simon Badger, Matteo Becchetti, Colomba Brancaccio +4
The production of a top-quark pair, the heaviest known elementary particle, in association with a light jet is a key process for studying the properties of the Standard Model of Pa…
One-Loop QCD Corrections to at
Matteo Becchetti, Maximilian Delto, Sara Ditsch +3
We present a computation of the one-loop QCD corrections to top-quark pair production in association with a boson, including terms up to order in dimensional re…
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…
