Correction exponents in the chiral Heisenberg model at : singular contributions and operator mixing
Alexander N. Manashov, Leonid A. Shumilov
We calculate the correction exponents in the chiral Heisenberg model in the expansion. These exponents are related to the slopes of functions at the phase transition poi…
Anomalous dimensions at small spins
A. N. Manashov, S. Moch, L. A. Shumilov
In perturbation theory, the anomalous dimensions of twist-two operators have poles at negative or small positive integer values of spin and therefore must be resummed at these poin…
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…
Resummation of small-spin singularities in anomalous dimensions of twist-two operators
Alexander N. Manashov, Sven-Olaf Moch, Leonid A. Shumilov
Anomalous dimensions of leading-twist operators in QCD play an important role in precision predictions for high-energy processes, since they govern the scale evolution of parton di…
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…
