Top-associated Higgs-boson production using perturbative fragmentation functions at next-to-leading-order
Colomba Brancaccio, Michal Czakon, Terry Generet +1
Under certain conditions, the production of a Higgs boson in association with a top-anti-top pair at hadron colliders can be described via a factorisation theorem using perturbativ…
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…
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…
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…
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…
