Description
The QCDSF collaboration has investigated the distribution amplitudes and wave function normalization constants of the nucleon and its parity partner, the N*(1535). In this talk, I will report on recent progress in the calculation of these quantities. The calculations have been performed on configurations with two dynamical flavors of O(a)-improved Wilson fermions. New data at pion masses of approximately 270 MeV helps in significantly reducing errors in the extrapolation to the physical point.
