A7. Baryonmassen, Resonanzen und Produktionsprozesse mit funktionalen Methoden
C.Fischer
In einem systematischen Zugang über Dyson-Schwinger, Bethe-Salpeter und Faddeev Gleichungen sowie einer allgemeinen Methode, zwei externe Ströme an Baryonen anzukoppeln, wollen wir Baryonmassen in Grund- und angeregten Zuständen bestimmen, ihre Formfaktoren berechnen, sowie die Methode auf Wirkungsquerschnitte von Produktionsprozessen anwenden. Durch Einbeziehung von Effekten der Mesonenwolken werden wir dabei wesentlich über die bisher verwendeten Regenbogen-Leiter Näherungen hinausgehen.
