Although nowadays many lattice QCD calculations are performed with up and down quark masses close to their physical values, the study of the quark mass dependence of hadronic observables is still of high interest for several reasons. First, there are still many lattice QCD calculations being done with light quark masses larger than their physical values. For these a chiral extrapolation is mandatory. Second, the dependence of the light quark mass of a certain flavor can be used to gain important insights into the internal structure of various hadrons. Third, the heavy quark mass dependence can be used to test to what extent heavy quark flavor symmetry (HQFS) can be used to make predictions of hadronic molecules formed by a pair of heavy hadrons. We want to study Wick contractions for meson-nucleon scattering processes and nucleon form factors in CHPT, the quark mass dependence of coupled-channel resonances, the role of HQFS for hadronic molecules and the θ-dependence of the binding energies of light nuclei.
