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…
Two-loop all-plus helicity amplitudes for self-dual Higgs boson with gluons via unitarity cut constraints
Simon Badger, Christian Biello, Colomba Brancaccio +1
We present the two-loop amplitudes for a self-dual Higgs boson with up to four positive helicity gluons in the heavy top-quark limit. Because the tree amplitudes in the all-plus se…
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…
Numerical evaluation of two-loop QCD helicity amplitudes for at leading colour
Simon Badger, Matteo Becchetti, Colomba Brancaccio +2
We present the first benchmark evaluation of the two-loop finite remainders for the production of a top-quark pair in association with a jet at hadron colliders in the gluon channe…
Two-loop amplitudes for corrections to production at the LHC
Simon Badger, Heribertus Bayu Hartanto, Zihao Wu +2
We present the two-loop helicity amplitudes contributing to the next-to-next-to-leading order QCD predictions for W-boson production in association with two photons at the Large Ha…
Progress Towards Two-loop QCD Corrections to
Simon Badger
We present the status of on-going efforts to compute the two-loop virtual corrections to in the leading colour approximation. We review the recent study of the m…
Two-loop integrals for jet production at hadron colliders in the leading colour approximation
Simon Badger, Matteo Becchetti, Nicolò Giraudo +1
We compute the differential equations for the two remaining integral topologies contributing to the leading colour two-loop amplitudes for . We derive dif…
Scattering Amplitudes in Quantum Field Theory
Simon Badger, Johannes Henn, Jan Plefka +1
These lecture notes bridge a gap between introductory quantum field theory (QFT) courses and state-of-the-art research in scattering amplitudes. They cover the path from basic defi…
