Conformal moments of the two-loop coefficient functions in DVCS

V. M. Braun, P. Gotzler, A. N. Manashov

We develop a new technique and calculate conformal (Gegenbauer) moments of the two-loop coefficient functions in Deeply Virtual Compton Scattering (DVCS). These results are necessa…

The $Î³^\ast\to Î·Î³$ and $Î³^\ast\to Î·'Î³$ form factors to NNLO accuracy in perturbative QCD

V. M. Braun, K. G. Chetyrkin, A. N. Manashov

We use conformal symmetry to calculate the NNLO anomalous dimension matrix (three loops) for flavor-singlet axial-vector QCD operators for spin $N \leq 8$ from a set of gauge-invari…

Kinematic power corrections to DVCS to twist-six accuracy

V. M. Braun, Yao Ji, A. N. Manashov

We calculate $(- t / Q)^{k}$ and $(m / Q)^{k}$ power corrections with $k \leq 4$ , where $m$ is the target mass and $t$ is the momentum transfer, to several key observables in Deeply V…
