Scale dependence of non-factorizable virtual corrections to Higgs boson production in weak boson fusion
Christian Brønnum-Hansen, Ming-Ming Long, Kirill Melnikov
The renormalization-scale dependence of the non-factorizable virtual corrections to Higgs boson production in weak boson fusion at next-to-next-to-leading order in perturbative QCD…
On the non-factorizable corrections to Higgs boson production in weak boson fusion
Konstantin Asteriadis, Christian Brønnum-Hansen, Kirill Melnikov
We discuss the non-factorizable corrections to Higgs boson production in weak boson fusion at the Large Hadron Collider. Such corrections depend on the finite part of the two-loop…
Non-factorisable contributions to -channel single-top production at the LHC and FCC
Christian Brønnum-Hansen, Jérémie Quarroz, Chiara Signorile-Signorile +1
Single top quark is mainly produced through the -channel W boson exchange at LHC. This process probes Wtb vertex directly and can be used to measure t…
Non-factorisable contribution to -channel single-top production
Christian Brønnum-Hansen, Kirill Melnikov, Jérémie Quarroz +2
We compute the non-factorisable corrections to -channel single-top quark production at the LHC. These peculiar corrections arise because of interactions betwee…
Non-factorisable two-loop contribution to -channel single-top production
Christian Brønnum-Hansen, Jérémie Quarroz, Chen-Yu Wang
We report on a recent computation of the non-factorisable contribution to the two-loop helicity amplitude for -channel single-top production arXiv:2108.09222. This is the last m…

Christian Brønnum-Hansen, Kirill Melnikov, Jérémie Quarroz +1
We compute the non-factorisable contribution to the two-loop helicity amplitude for -channel single-top production, the last missing piece of the two-loop virtual corrections to…
Virtual QCD corrections to gluon-initiated diphoton plus jet production at hadron colliders
Simon Badger, Christian Brønnum-Hansen, Dmitry Chicherin +7
We present an analytic computation of the gluon-initiated contribution to diphoton plus jet production at hadron colliders up to two loops in QCD. We reconstruct the analytic form…
Top quark contribution to two-loop helicity amplitudes for boson pair production in gluon fusion
Christian Brønnum-Hansen, Chen-Yu Wang
We compute the top quark contribution to the two-loop amplitude for on-shell boson pair production in gluon fusion, . Exact dependence on the top quark mass is retai…

Christian Brønnum-Hansen, Chen-Yu Wang
We compute the contribution of third generation quarks () to the two-loop amplitude for on-shell boson pair production in gluon fusion . We present plots for…
A numerical evaluation of planar two-loop helicity amplitudes for a W-boson plus four partons
Heribertus Bayu Hartanto, Simon Badger, Christian Brønnum-Hansen +1
We present the first numerical results for the two-loop helicity amplitudes for the scattering of four partons and a W-boson in QCD. We use a finite field sampling method to reduce…
Analytic helicity amplitudes for two-loop five-gluon scattering: the single-minus case
Simon Badger, Christian Brønnum-Hansen, Heribertus Bayu Hartanto +1
We present a compact analytic expression for the leading colour two-loop five-gluon amplitude in Yang-Mills theory with a single negative helicity and four positive helicities. The…
Applications of integrand reduction to two-loop five-point scattering amplitudes in QCD
Simon Badger, Christian Brønnum-Hansen, Thomas Gehrmann +4
We review the current state-of-the-art in integrand level reduction for five-point scattering amplitudes at two loops in QCD. We present some benchmark results for the evaluation o…
A first look at two-loop five-gluon scattering in QCD
Simon Badger, Christian Brønnum-Hansen, Heribertus Bayu Hartanto +1
We compute the leading colour contributions to five-gluon scattering at two loops in massless QCD. The integrands of all independent helicity amplitudes are evaluated using d-dimen…
A unitarity compatible approach to one-loop amplitudes with massive fermions
Simon Badger, Christian Brønnum-Hansen, Francesco Buciuni +1
We explain how one-loop amplitudes with massive fermions can be computed using only on-shell information. We first use the spinor-helicity formalism in six dimensions to perform ge…
