Zusammenfassung
Light-Cone Sum Rules (LCSRs) have become an established technique for the QCD calculation of hadronic form factors and relatedobservables in the range of intermediate momentum transfers, of the order of a few~GeV
. 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 thenext-to-leading order (NLO) in the strong coupling, which has becomestandard for meson decays.
