Nucleon and meson matrix elements close to the physical point

The introduction to this project is given in the report for project pr85xi ''Excited state artifacts in calculations of hadron 3-point functions''. We focus here on the discussion of more results. As explained in the report for pr85xi, we have found clear evidence that present day lattice simulations are still plagued by more severe artifacts than previously assumed. Thus, we will concentrate in this report on applications for which so little is known physics-wise that even lattice results with a possible non-negligible remaining systematic error due to discretization effects are very valuable.
