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 \…
The -extension of iterated integrals and nested sums in quantum field theory
J. Blümlein, A. M. Gavrilik, O. Mykhailiv +1
Analytic calculations of zero- and single-scale quantities in perturbative quantum field theory result into special numbers and functions, the first of which have been revealed dur…
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…
The three-loop single-mass heavy flavor corrections to deep-inelastic scattering
J. Ablinger, A. Behring, J. Blümlein +4
We report on the status of the calculation of the massive Wilson coefficients and operator matrix elements for deep-inelastic scatterung to three-loop order. We discuss both the un…
Next-to-Next-to-Leading Order Evolution of Polarized Parton Densities in the Larin Scheme
J. Blümlein, M. Saragnese
In many calculations involving polarized twist-2 parton densities to higher order in the strong coupling constant one uses the Larin scheme to describe chiral effects in dimensiona…
