NNLO QCD corrections to the weak radiative -meson decay with exact dependence on
M. Czaja, M. Czakon, T. Huber +5
The inclusive weak radiative -meson decay provides important constraints on many popular extensions of the Standard Model. Some of the numerically relevant Next-to-Next-to-Leadi…
The inclusive decay rate with higher precision
M. Misiak, H. M. Asatrian, K. Brune +11
We present a new and upgraded analysis of the inclusive weak radiative decay of the meson in the standard model and beyond. The perturbative corrections are…
Three-loop QCD+QED corrections to on-shell quark renormalization
Long Chen, Hong-Yang Han, Zhe Li +1
We present the three-loop QCD+QED mixed corrections to the on-shell quark mass and wave-function renormalization constants through orders with . We f…
On-shell Matrix Elements of the EMT Trace in Gauge Theories and Heavy Quark Masses
Long Chen, Zhe Li, Marco Niggetiedt
We present a novel diagrammatic proof of the identity between the forward matrix element of the energy-momentum-tensor (EMT) trace operator over a single particle's on-shell state…
Precision tests of third-generation four-quark operators: and
Ulrich Haisch, Marco Niggetiedt
We compute the two-loop contributions to Higgs production via gluon-gluon fusion () and Higgs decay into two photons (), arising from third-generation four-quar…
Three-loop QCD Mass Relation between the and Symmetric-momentum Subtraction Scheme Away from the Chiral Limit
Long Chen, Marco Niggetiedt
The perturbative result for the quark-mass conversion factor between the and regularization-independent symmetric-momentum subtraction scheme (RI/SMOM) awa…
Renormalization of the pseudoscalar operator at four loops in QCD
Long Chen, Michał Czakon, Marco Niggetiedt
We present the renormalization constant of the pseudoscalar operator defined with a non-anticommuting in dimensional regularization up to four-loop order in perturbative Quan…
Exact two-loop amplitudes for Higgs plus jet production with a cubic Higgs self-coupling
Ulrich Haisch, Marco Niggetiedt
We compute the corrections to the two-loop amplitudes for , , , and due to a modified cubic Higgs self-coupling. The exact depende…
Quark Mass Effects in Higgs Production
Michał Czakon, Felix Eschment, Marco Niggetiedt +2
We examine the effect of finite top- and bottom-quark masses on the Higgs production cross section in the gluon-gluon fusion channel. We employ both and on-s…
Higgs-boson production in the full theory at NNLO+PS
Marco Niggetiedt, Marius Wiesemann
We consider the production of a Standard-Model (SM) Higgs boson in gluon fusion in hadronic collisions and compute the QCD corrections up to next-to-next-to-leading order (NNLO) an…
Top-Bottom Interference Contribution to Fully-Inclusive Higgs Production
Michał Czakon, Felix Eschment, Marco Niggetiedt +2
We evaluate the top-bottom interference contribution to the fully-inclusive Higgs production cross section at next-to-next-to-leading order in QCD. Although bottom-quark-mass effec…
The Higgs-gluon form factor at three loops in QCD with three mass scales
Marco Niggetiedt, Johann Usovitsch
We report on the complete three-loop corrections to the Higgs-gluon form factor in QCD. While previous calculations are based on QCD with a single heavy quark of arbitrary mass, we…
The complete singlet contribution to the massless quark form factor at three loops in QCD
Long Chen, Michał Czakon, Marco Niggetiedt
It is well known that the effect of top quark loop corrections in the axial part of quark form factors (FF) does not decouple in the large top mass or low energy limit due to the p…
Exact top-quark mass dependence in hadronic Higgs production
M. Czakon, R. V. Harlander, J. Klappert +1
The impact of the finite top-quark mass on the inclusive Higgs production cross section at higher perturbative orders has been an open question for almost three decades. In this pa…
Exact quark-mass dependence of the Higgs-gluon form factor at three loops in QCD
M. Czakon, M. Niggetiedt
We determine the three-loop form factor parameterising the amplitude for the production of an off-shell Higgs boson in gluon fusion in QCD with a single massive quark. The result i…
