1. Theoretical Studies of Hadronic Reactions with Vector Mesons
Sammanfattning : Aiming at a systematic inclusion of pseudoscalar and vector mesons as active degrees of freedom in an effective Lagrangian, studies have been performed in this thesis concerning the foundations of such an effective Lagrangian as well as tree-level and beyond-tree-level calculations. Hereby, vector mesons are described by antisymmetric tensor fields. LÄS MER
2. Isomeric yield ratio studies in nuclear reactions and alpha-particle induced fission of Thorium
Sammanfattning : Despite decades of research since the initial discovery of nuclear fission, numerous unresolved questions still persist. It is known empirically that fission fragments emerge with high angular momentum. The mechanism responsible for the generation of the large angular momenta observed is one of these open questions.

3. The interplay between quark and hadronic degrees of freedom and the structure of the proton
Sammanfattning : We study the low-energy sector of the strong interaction which is the least understood part of the Standard Model, the theory that describes the interactions of all known particles. The ideal particles for this study are the proton and the neutron, collectively called the nucleon. LÄS MER
4. Electromagnetic and Spin Properties of Hyperons
Sammanfattning : The study of hyperons improves our understanding of nature in multiple ways. The intrinsic properties of hadrons are not fully understood at a fundamental level. Hence, the electromagnetic properties of hyperons provide complementary information to that of the nucleon and therefore allow for a broader investigation of the structure of matter. LÄS MER
