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 $γ^\ast\to ηγ$ and $γ^\ast\to η'γ$ 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 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 and power corrections with , where is the target mass and is the momentum transfer, to several key observables in Deeply V…
The two-loop coefficient functions for double deeply virtual Compton scattering
Vladimir M. Braun, Hua-Yu Jiang, Alexander N. Manashov +1
Making use of conformal symmetry of large- QCD in dimensions at the Wilson-Fischer fixed point, we calculate the two-loop coefficient functions in the operator produ…
