Three-loop off-forward evolution kernel for axial-vector operators in Larin's scheme
V. M. Braun, A. N. Manashov, S. Moch +1
Evolution equations for leading twist operators in high orders of perturbation theory can be restored from the spectrum of anomalous dimensions and the calculation of the special c…
Two-loop evolution equations for flavor-singlet light-ray operators
V. M. Braun, A. N. Manashov, S. Moch +1
QCD in non-integer space-time dimensions enjoys conformal invariance at the special fine-tuned value of the coupling. Counterterms for composite operators in minimal subtr…
B form factors with light-cone sum rules
Maximilian Emmerich, Matthias Strohmaier, Andreas Schäfer
We construct the quark-antiquark chiral odd distribution amplitudes including twist-four mass contributions for tensor mesons. We also give quark-antiquark-gluon distribution ampli…
Electroproduction of tensor mesons in QCD
V. M. Braun, N. Kivel, M. Strohmaier +1
Due to multiple possible polarizations hard exclusive production of tensor mesons by virtual photons or in heavy meson decays offers interesting possibilities to study the helicity…
