Higher Order Heavy Quark Corrections to Deep-Inelastic Scattering
J. Blümlein, A. De Freitas, C. Schneider
The 3-loop heavy flavor corrections to deep-inelastic scattering are essential for consistent next-to-next-to-leading order QCD analyses. We report on the present status of the cal…
3-loop Massive Contributions to the DIS Operator Matrix Element
J. Ablinger, J. Blümlein, A. De Freitas +4
Contributions to heavy flavour transition matrix elements in the variable flavour number scheme are considered at 3-loop order. In particular a calculation of the diagrams with two…
