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…
-Jettiness Soft Functions Made Simple
Luca Buonocore, Maximilian Delto, Kirill Melnikov +3
We present a new method to compute the soft function for the -Jettiness variable for arbitrary at high perturbative orders in QCD. It is based on the observation that the mo…
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…
High-Energy Evolution of Power-Suppressed Amplitudes
Maximilian Delto, Alexander Penin, Lorenzo Tancredi
We present a new class of evolution equations which govern the high-energy behavior of power-suppressed scattering amplitudes. The equations can be viewed as a renormalization grou…
Triple real-emission contribution to the zero-jettiness soft function at N3LO in QCD
Daniel Baranowski, Maximilian Delto, Kirill Melnikov +2
Recently, we have presented the result for the zero-jettiness soft function at next-to-next-to-next-to-leading order (N3LO) in perturbative QCD [arXiv:2409.11042], without providin…
