Abstract (English)

In this work we develop a systematic approach to calculate moments of leading-twist and next-to-leading twist baryon distribution amplitudes within lattice QCD. Using two flavours of dynamical clover fermions we determine low moments of nucleon distribution amplitudes as well as constants relevant for proton decay calculations in grand unified theories. The deviations of the leading-twist nucleon ...

In dieser Arbeit entwickeln wir einen systematischen Zugang zur Berechnung der Momente der Nukleondistributionsamplitude im führendem Twist im Rahmen der Gitter QCD. Wir bestimmen die niedrigsten Momente unter Benutzung der dynamischen zwei flavor Clover fermionen, so wie auch für Nukleonzerfall in GUT relavante Konstanten. Die erhaltene Abweichung von der asymptotischen Form ist deutlich weniger ...
