1) Structure functions and form factors:The QCDSF colaboration has long standing experience in the calculation of moments of structure functions and form factors. We plan to use the newly generated dynamical configurations to recalculate these, taking also disconnected graphs into account. We also want to extend these studies to moments of Skewed Parton Distributions.2) Chirally improved and perfect action:Chirally symmetric lattice formulations became possible some years ago. We already used a particular chirally improved action to study e.g. the properties of instantions and calorons. We plan to extend these studies to a perfect action and overlap fermions and to calculate a number of observables for all three actions.
