Difference Equations in Massive Higher Order Calculations
I. Bierenbaum, J. Blümlein, S. Klein +1
The calculation of massive 2--loop operator matrix elements, required for the higher order Wilson coefficients for heavy flavor production in deeply inelastic scattering, leads to…
Two-Loop Massive Operator Matrix Elements for Polarized and Unpolarized Deep-Inelastic Scattering
I. Bierenbaum, J. Blümlein, S. Klein
The massive operator matrix elements for unpolarized and polarized heavy flavor production at asymptotic values are calculated in Mellin space without apply…
Structural Relations between Harmonic Sums up to w=6
Johannes Blümlein, Sebastian Klein
Multiply nested finite harmonic sums occur in many single scale higher order calculations in Quantum Field Theory. We discuss their algebraic and structural re…
Two-Loop Massive Operator Matrix Elements and Unpolarized Heavy Flavor Production at Asymptotic Values Q^2 >> m^2
Isabella Bierenbaum, Johannes Blümlein, Sebastian Klein
We calculate the massive operator matrix elements for the twist--2 operators, which contribute to the heavy flavor Wilson coefficients in unpolarized deeply inelastic sc…
