W-Boson Production in Association with a Jet at Next-to-Next-to-Leading Order in Perturbative QCD. [PDF]
Physical Review Letters, 2015 We present the complete calculation of W-boson production in association with a jet in hadronic collisions through next-to-next-to-leading order (NNLO) in perturbative QCD. To cancel infrared divergences, we discuss a new subtraction method that exploits

NLO EW and QCD corrections to polarised same-sign WW scattering at the LHC
Journal of High Energy PhysicsWe present the first calculation of same-sign WW scattering at the LHC in the fully leptonic decay channel including the modelling of polarisation for intermediate electroweak bosons and radiative corrections up to NLO EW+QCD accuracy.

Three-loop master integrals for the Higgs boson self-energy with internal top-quarks and W-bosons
Journal of High Energy Physics, 2022 We consider the full set of master integrals with internal top-and W-propagators contributing to the three-loop Higgs self-energy diagrams of order O $$ \mathcal{O} $$ (α 2 α s ).

Finite scattering amplitudes in field theory [PDF]
, 2007 In this thesis we explore the infrared problem perturbatively in massless field theory. We review the current conventional methods and theorems that are applied in the calculation of QCD jet observables and then discuss the formulation of an alternative ...

Perturbative QCD at the LHC [PDF]
, 2014 In this brief overview, we discuss selected topics of perturbative QCD at the Large Hadron Collider (LHC). In particular we presents some recent results on parton densities, higher-order calculations, Sudakov resummation and parton ...

Two-loop mixed QCD-electroweak amplitudes for Z+jet production at the LHC: bosonic corrections
Journal of High Energy PhysicsWe present a calculation of the bosonic contribution to the two-loop mixed QCD-electroweak scattering amplitudes for Z-boson production in association with one hard jet at hadron colliders.

Master integrals for O $$ \mathcal{O} $$ (αα s ) corrections to H → ZZ *
Journal of High Energy Physics, 2022 We present analytic results for all the Feynman integrals relevant for O $$ \mathcal{O} $$ (αα s ) virtual corrections to H → ZZ * decay. We use the method of differential equations to solve the master integrals while keeping the full dependence on the ...

Quark and Gluon Form Factors at Three Loops in Perturbative QCD [PDF]
, 2009 We compute the quark and gluon form factors at up to three-loop order within massless perturbative Quantum Chromodynamics by studying the photon-quark-anti-quark vertex and the effective vertex of a Higgs boson and two gluons.

Higher-order non-global logarithms from jet calculus
, 2021 Non-global QCD observables are characterised by a sensitivity to the full angular distribution of soft radiation emitted coherently in hard scattering processes. This complexity poses a challenge to their all-order resummation, that was formulated at the

Precision phenomenology at multi-TeV muon colliders
Journal of High Energy PhysicsFuture lepton colliders, such as those based on linear e + e − or circular μ + μ − accelerators, are expected to attain centre-of-mass energies in the multi-TeV range.
