Conformal symmetry of QCD is restored at the Wilson-Fisher critical point in noninteger space-time dimensions. Correlation functions of multiplicatively renormalizable operators with different anomalous dimensions at the critical point vanish identically.

We show that this property allows one to calculate off-diagonal parts of the anomalous dimension matrices for leading-twist operators from...

I derive an all-order resummation formula for the logarithmically enhanced contributions proportional to αsnx±ξ \frac{\alpha_s^n}{x\pm \xi } x±ξαsn log (ξ±x2ξ)k {\left(\frac{\xi \pm x}{2\xi}\right)}^k (2ξξ±x)k in the quark coefficient function of deeply-virtual-Compton scattering and the pion-photon transition form factor in momentum space. The resummation is performed at the...

We will discuss the gluon GPD from moderate to small x using partial twist expansion.

Generalized Transverse Momentum Dependent (GTMD) distributions provide the most complete information on the structure of hadrons one can hope to constrain via experiments described in perturbative QCD. Using their Fourier transforms, Wigner distributions, it is possible to write very intuitive definitions for some physical properties inside hadrons such as the decomposition of its spin between...

Both deeply-virtual and photoproduction of mesons offer promising access

to generalized parton distributions and complementary description of different kinematical regions. Higher-twist effects have been identified as especially important in the case of the production of pseudo-scalar mesons. This was confirmed by recent evaluation of the complete twist-3 contribution to π production and its...
