| Abstract: |
In this thesis, the significance of t- and u-channel exchange processes in the formation of axial-vector mesons is studied. The analysis is based on a chiral Lagrangian for light vector mesons. A non-linear integral equation based on unitarity and causality is used to unitarize the scattering amplitude. This leads to the formation of axial-vector molecules. |

Untersucht wird die Bedeutung von t- und u-Kanal Austauschprozessen bei der Erzeugung von Axialvektormesonen. Die Analyse basiert auf einem chiralen Lagrangian für leichte Vektormesonen. Eine nicht-lineare Integralgleichung, die auf Unitarität und Kausalität basiert, wird verwendet, um die Streuamplitude zu unitarisieren. Dies führt zur Entstehung von Axialvektor-Molekülen. | German |
