Abstract (English)

Higher-twist effects are relevant for precision calculations of hard exclusive reactions. Furthermore, they reveal fine details of the hadron structure. In this work we construct an operator basis for arbitrary twist respecting the conformal symmetry of QCD (which is realized on 1-loop level). Using this basis the 1-loop renormalization kernels of twist 4 are constructed for baryon operators. The ...

In dieser Arbeit konstruieren wir eine Operatorbasis beliebigen Twistes, die die auf 1-Schleifenniveau gegebene konforme Symmetrie der QCD respektiert. Mit ihrer Hilfe werden die die 1-Schleifen-Renormierungskerne für ...
