Top-quark pair production near threshold at LHC
Y. Kiyo, J. H. Kühn, S. Moch +2
The next-to-leading order analysis for the cross section for hadroproduction of top quark pairs close to threshold is presented. Within the framework of non-relativistic QCD a sign…
corrections to the vertex at the top quark threshold
Yuichiro Kiyo, Dirk Seidel, Matthias Steinhauser
We compute the last missing piece of the two-loop corrections to vertex at the threshold due to the exchange of a boson and a gluon. T…
Fermionic contributions to the three-loop static potential
Alexander V. Smirnov, Vladimir A. Smirnov, Matthias Steinhauser
We consider the three-loop corrections to the static potential which are induced by a closed fermion loop. For the reduction of the occurring integrals a combination of the Gröbner…
Precise Determinations of the Charm Quark Mass
Matthias Steinhauser
In this contribution two recent analyses for the extraction of the charm quark mass are discussed. Although they rely on completely different experimental and theoretical input the…
Evaluating the three-loop static quark potential
Alexander V. Smirnov, Vladimir A. Smirnov, Matthias Steinhauser
This is a status report of the evaluation of the three-loop corrections to the static QCD potential of a heavy quark and an antiquark. The families of Feynman integrals that appear…
Applying Mellin-Barnes technique and Groebner bases to the three-loop static potential
Alexander V. Smirnov, Vladimir A. Smirnov, Matthias Steinhauser
The Mellin-Barnes technique to evaluate master integrals and the algorithm called FIRE to solve IBP relations with the help of Groebner bases are briefly reviewed. In FIRE, an exte…
Higgs boson mass in supersymmetry to three loops
R. V. Harlander, P. Kant, L. Mihaila +1
Within the minimal supersymmetric extension of the Standard Model, the mass of the light CP-even Higgs boson is computed to three-loop accuracy, taking into account the next-to-nex…
Ghost contributions to charmonium production in polarized high-energy collisions
M. Klasen, B. A. Kniehl, L. N. Mihaila +1
In a previous paper [Phys. Rev. D 68, 034017 (2003)], we investigated the inclusive production of prompt J/psi mesons in polarized hadron-hadron, photon-hadron, and photon-photon c…
