Quark distribution amplitudes and form factors of the nucleon resonances in QCD

Light-Cone Sum Rules (LCSRs) have become an established technique for the QCD calculation of hadronic form factors and related observables in the range of intermediate momentum transfers, of the order of a few GeV². However, for processes involving baryons the sum rules exist to the tree level only, which roughly corresponds to the approximation of the parton model. The goal of this project is to advance such calculations to the next-to-leading order (NLO) in the strong coupling, which has become standard for meson decays.
