Towards NNLO QCD corrections to Higgs boson pair production
Matthias Steinhauser
Higgs boson pair production plays an important role in the determination of the Higgs boson self coupling. The predictions based on next-to-leading order corrections show a large d…
Electroweak corrections to : Factorizable contributions
Joshua Davies, Kay Schönwald, Matthias Steinhauser +1
In these proceedings, we consider the factorizable contributions of the two-loop electroweak corrections to Higgs boson pair production at the Large Hadron Collider. We discuss the…
Three-loop corrections to Higgs boson pair production: reducible contribution
Joshua Davies, Kay Schönwald, Matthias Steinhauser +1
We compute three-loop corrections to the process originating from one-particle reducible diagrams. This requires the computation of two-loop corrections to the gluon-glu…
Minimal Supersymmetric SU(5) and Gauge Coupling Unification at Three Loops
W. Martens, L. Mihaila, J. Salomon +1
We consider the relations between the gauge couplings at the electroweak scale and the high scale where unification of the three gauge couplings is expected. Threshold corrections…
Light MSSM Higgs boson mass to three-loop accuracy
P. Kant, R. V. Harlander, L. Mihaila +1
The light CP even Higgs boson mass, Mh, is calculated to three-loop accuracy within the Minimal Supersymmetric Standard Model (MSSM). The result is expressed in terms of DRbar para…
Dimensional Reduction applied to QCD at three loops
R. Harlander, P. Kant, L. Mihaila +1
Dimensional Reduction is applied to \qcd{} in order to compute various renormalization constants in the \drbar{} scheme at higher orders in perturbation theory. In particular, the…
Two-Loop Matching Coefficients for Heavy Quark Currents
B. A. Kniehl, A. Onishchenko, J. H. Piclum +1
In this paper we consider the matching coefficients up to two loops between Quantum Chromodynamics (QCD) and Non-Relativistic QCD (NRQCD) for the vector, axial-vector, scalar and p…
J/psi plus prompt-photon associated production in two-photon collisions at next-to-leading order
M. Klasen, B. A. Kniehl, L. N. Mihaila +1
We calculate the cross section of J/psi plus prompt-photon inclusive production in gamma gamma collisions at next-to-leading order within the factorization formalism of nonrelativi…
The Impact of Measurements at Intermediate Energies on the Parameters of the Standard Model
J. H. Kühn, M. Steinhauser
We discuss the impact of precision measurements of in the center-of-mass range between 3 and 12 GeV, including improvements in the electronic widths of the…
J/psi plus dijet associated production in two-photon collisions
M. Klasen, B. A. Kniehl, L. Mihaila +1
We study the production of a J/psi meson in association with one or two jets in gamma gamma collisions concentrating on the direct-photon contribution, which is expected to be domi…
O(α_s^2) Corrections to Top Quark Production at Colliders
R. Harlander, M. Steinhauser
In this article we evaluate mass corrections up to to the three-loop polarization function induced by an axial-vector current. Special emphasis is put on the evalu…
Mass Corrections to the Vector Current Correlator
K. G. Chetyrkin, R. Harlander, J. H. Kuehn +1
Three-loop QCD corrections to the vector current correlator are considered. The large momentum procedure is applied in order to evaluate mass corrections up to order .…
Automatic Computation Of Three-Loop Two-Point Functions In Large Momentum Expansion
K. G. Chetyrkin, R. Harlander, J. H. Kuehn +1
We discuss the calculation of two-point three-loop functions with an arbitrary number of massive propagators and one large external momentum. The relevant subdiagrams are generated…
