Towards analytic at four loops
Matthias Steinhauser
In this contribution we present recent four-loop results for the muon anomalous magnetic moment based on analytic methods. In particular, fermionic corrections involving two or mor…
Anomalous magnetic moment with heavy virtual leptons
Alexander Kurz, Tao Liu, Peter Marquard +1
We compute the contributions to the electron and muon anomalous magnetic moment induced by heavy leptons up to four-loop order. Asymptotic expansion is applied to obtain three anal…
Three-loop QCD corrections to B_s -> mu^+ mu^-
Thomas Hermann, Mikolaj Misiak, Matthias Steinhauser
The decay B_s -> mu^+ mu^- in the Standard Model is generated by the well-known W-box and Z-penguin diagrams that give rise to an effective quark-lepton operator Q_A at low energie…
B_{s,d} -> l+ l- in the Standard Model with Reduced Theoretical Uncertainty
Christoph Bobeth, Martin Gorbahn, Thomas Hermann +3
We combine our new results for the O(alpha_em) and O(alpha_s^2) corrections to B_{s,d} -> l^+ l^-, and present updated branching ratio predictions for these decays in the standard…
Colour octet potential to three loops
Chihaya Anzai, Mario Prausa, Alexander V. Smirnov +2
We consider the interaction between two static sources in the colour octet configuration and compute the potential to three loops. Special emphasis is put on the treatment of pinch…
MT: a Mathematica package to compute convolutions
Maik Hoeschele, Jens Hoff, Alexey Pak +2
We introduce the \prog{Mathematica} package \prog{MT} which can be used to compute, both analytically and numerically, convolutions involving harmonic polylogarithms, polynomials o…
Higgs boson production in the SM and MSSM to NNLO and beyond
Matthias Steinhauser
In this contribution a brief review about the status of higher order corrections to Higgs boson production within the Minimal Supersymmetric Standard Model (MSSM) is given. Further…
On the Higgs boson pair production at the LHC
Jonathan Grigo, Jens Hoff, Kirill Melnikov +1
We compute the production cross section of a pair of Standard Model Higgs bosons at the LHC at next-to-leading order in QCD, including corrections in inverse powers of the top quar…
Four-loop corrections with two closed fermion loops to fermion self energies and the lepton anomalous magnetic moment
Roman Lee, Peter Marquard, Alexander V. Smirnov +2
We compute the eighth-order fermionic corrections involving two and three closed massless fermion loops to the anomalous magnetic moment of the muon. The required four-loop on-shel…
