1. Theorists and Lattice QCD groups should work closer together and combine their expertise in hadron physics. 2. Lattice QCD groups should, next to flavor-SU(3), also consider flavor-SU(2) ensembles, since the limitation to two quarks leads to simpler results from flavor-SU(2) Chiral Perturbation Theory. 3. The use of on-shell masses in loop contributions leads to a new phenomenon, the non-analytical behavior of masses and form factors, which
conventional schemes of Chiral Perturbation Theory cannot
describe. 4. In order to scrutinize the non-analytic behavior, which arises from the use of on-shell masses in the loop contributions, lattice groups should not only focus on the determination of baryon masses, but also on form factors. 5. Experimentally non-accessible axial-vector form factors should be determined on the lattice for a better understanding of the success of the Cabibbo model and its limitations. 6. Double Degree PhD programs offer great
opportunities for all parties involved, but the universities should define clear rules, in particular for the transition period at half time. 7. The Van Swinderen Institute should consider establishing mixed offices with master students and PhD students in order to facilitate scientific discussions, from which both sides would benefit.
