note = {This thesis is a collection of studies concerned with the phenomenology of the Θ-angle of quantum chromodynamics (QCD) at values 0 < Θ < π, and of the axion in nuclear and particle physics. In the first part, the consequences of a non-vanishing Θ-angle for nuclear physics are determined with respect to the nucleon masses, the binding energies of light nuclei, and the process of nucleosynthesis. In the second part, the interaction of axions with photons and baryons is examined making use of chiral perturbation theory, the low-energy effective field theory of the strong interaction part of the Standard Model. Finally, these insights are used to determine the cross section of pion axioproduction with contributions from the Δ resonance. All these studies hence are related to a flaw of the Standard Model of Particle Physics known in the literature as the “strong CP problem”. In particular, the latter studies are contributions to the search of axions.},
