The Heavy Quark Form Factors at Two Loops
J. Ablinger, A. Behring, J. Blümlein +5
We compute the two-loop QCD corrections to the heavy quark form factors in case of the vector, axial-vector, scalar and pseudo-scalar currents up to second order in the dimensional…
The massive 3-loop operator matrix elements with two masses and the generalized variable flavor number scheme
J. Ablinger, J. Blümlein, A. De Freitas +4
We report on our latest results in the calculation of the two--mass contributions to 3--loop operator matrix elements (OMEs). These OMEs are needed to compute the corresponding con…
Iterative and Iterative-Noniterative Integral Solutions in 3-Loop Massive QCD Calculations
J. Ablinger, A. Behring, J. Blümlein +6
Various of the single scale quantities in massless and massive QCD up to 3-loop order can be expressed by iterative integrals over certain classes of alphabets, from the harmonic p…
Heavy Flavor Wilson Coefficients in Deep-Inelastic Scattering: Recent Results
J. Ablinger, A. Behring, J. Blümlein +3
We present recent analytic results for the 3-loop corrections to the massive operator matrix element for further color factors. These results have been obtained using…
The two-mass contribution to the three-loop pure singlet operator matrix element
J. Ablinger, J. Blümlein, A. De Freitas +2
We present the two-mass QCD contributions to the pure singlet operator matrix element at three loop order in x-space. These terms are relevant for calculating the structure functio…
Heavy quark form factors at two loops in perturbative QCD
J. Ablinger, A. Behring, J. Blümlein +5
We present the results for heavy quark form factors at two-loop order in perturbative QCD for different currents, namely vector, axial-vector, scalar and pseudo-scalar currents, up…
