Relations between electroweak parameters to order
Andreas Maier, Peter Marquard
Relations between electroweak parameters can be measured with ever-increasing precision and a future lepton collider will require major advances in the theoretical predictions. We…
Holonomic techniques for massive 3-loop form factors: the gluonic case
J. Blümlein, A. De Freitas, P. Marquard +2
Massive three-loop form factors for vector, axial-vector, scalar, and pseudoscalar currents are vital for precision collider phenomenology. Extending the quarkonic framework to the…
Analytic results on the massive three-loop form factors: gluonic contributions
J. Blümlein, A. De Freitas, P. Marquard +2
We compute the gluonic contributions to the three-loop heavy-quark form factors for the vector, axial-vector, scalar, and pseudoscalar currents. In the low-energy limit, $q^2/m^2 \…
Challenges for analytic calculations of the massive three-loop form factors
J Blümlein, A. De Freitas, P. Marquard +1
The calculation of massive three-loop QCD form factors using in particular the large moments method has been successfully applied to quarkonic contributions in [1]. We give a brief…
Towards QCD at Five Loops
Andreas Maier, Peter Marquard, York Schröder
We report on recent progress on five-loop calculations in perturbative QCD. We discuss the computation of the perturbative quark condensate, decoupling in QCD, and the precision de…
Analytic results on the massive three-loop form factors: quarkonic contributions
Johannes Blümlein, Abilio De Freitas, Peter Marquard +2
The quarkonic contributions to the three-loop heavy-quark form factors for vector, axial-vector, scalar and pseudoscalar currents are described by closed form difference equations…
