Higher order hadronic and leptonic contributions to the muon
Alexander Kurz, Tao Liu, Peter Marquard +3
In this contribution we discuss next-to-next-to-leading order hadronic and four-loop QED contributions to the anomalous magnetic moment of the muon.
to order
Luminita Mihaila, Barbara Schmidt, Matthias Steinhauser
We compute the decay rate of the Standard Model Higgs boson to bottom quarks to order . We apply the optical theorem and calculate the imaginary part of three-loop correction…
Higgs boson pair production: top quark mass effects at NLO and NNLO
Jonathan Grigo, Jens Hoff, Matthias Steinhauser
We compute next-to-next-to-leading order QCD corrections to the gluon-induced production cross section of Higgs boson pairs in the large top quark mass limit using the soft-virtual…
Light-by-light-type corrections to the muon anomalous magnetic moment at four-loop order
Alexander Kurz, Tao Liu, Peter Marquard +3
The numerically dominant QED contributions to the anomalous magnetic moment of the muon stem from Feynman diagrams with internal electron loops. We consider such corrections and pr…
Non-relativistic high-energy physics: top production and dark matter annihilation
Martin Beneke, Matthias Steinhauser
Non-relativistic physics is often associated with atomic physics and low-energy phenomena of the strong interactions between nuclei and quarks. In this review we cover three topics…
Next-to-next-to-next-to-leading order QCD prediction for the top anti-top S-wave pair production cross section near threshold in e+ e- annihilation
Martin Beneke, Yuichiro Kiyo, Peter Marquard +3
We present the third-order QCD prediction for the production of top-anti-top quark pairs in electron-positron collisions close to the threshold in the dominant S-wave state. We obs…
Exact NLO results for
Chihaya Anzai, Alexander Hasselhuhn, Maik Höschele +4
We compute the contribution to the total cross section for the inclusive production of a Standard Model Higgs boson induced by two quarks with different flavour in the initial stat…
The (Q_7,Q_{1,2}) contribution to B -> X_s gamma at O(alpha_s^2)
Michal Czakon, Paul Fiedler, Tobias Huber +3
Interference between the photonic dipole operator Q_7 and the current-current operators Q_{1,2} gives one of the most important QCD corrections to the B -> X_s gamma decay rate. So…
Updated NNLO QCD predictions for the weak radiative B-meson decays
M. Misiak, H. M. Asatrian, R. Boughezal +15
Weak radiative decays of the B mesons belong to the most important flavor changing processes that provide constraints on physics at the TeV scale. In the derivation of such constra…
Decoupling of heavy quarks at four loops and effective Higgs-fermion coupling
Tao Liu, Matthias Steinhauser
We compute the decoupling constant relating light quark masses of effective -flavour QCD to -flavour QCD to four-loop order. Immediate applications are the eval…
Quark mass relations to four-loop order
Peter Marquard, Alexander V. Smirnov, Vladimir A. Smirnov +1
We present results for the relation between a heavy quark mass defined in the on-shell and scheme to four-loop order. The method to compute the four-loop on-shell in…
Massive Tadpoles: Techniques and Applications
Konstantin G. Chetyrkin, Johann H. Kühn, Matthias Steinhauser +1
A brief discussion of massive tadpole diagrams and their phenomenological consequences is presented. This includes predictions of the parameter and, as a consequence, the mass…
Selected topics on multi-loop calculations to Higgs boson properties and renormalization group functions
Luminita N. Mihaila, Matthias Steinhauser
We review some results obtained in the context of the Collaborative Research Center/Transregio~9. In particular we discuss three-loop corrections to the Higgs boson mass in the Min…
Parallel versions of FORM and more
Matthias Steinhauser, Takahiro Ueda, Jos A. M. Vermaseren
We review the status of the parallel versions of the computer algebra system FORM. In particular, we provide a brief overview about the historical developments, discuss the strengt…
