The nucleons, as one of the most fundamental building blocks of visible matter, are built up of quarks and gluons. However, the interactions and dynamics inside the nucleons, which are mediated by the strong force and ......

The photoproduction of mesons off the nucleon provides an excellent tool to gain further insight into the structure of baryons and their excitation spectrum. A large number of final states yielding various resonance ...

Photoproduction of heavy quarks in events with two jets has been measured with the ZEUS detector at HERA using data recorded in the years 2006-2007 corresponding to an integrated luminosity of 128 pb^-1. The ...

Zur Untersuchung der starken Wechselwirkung im störungstheoretisch nicht behandelbaren Bereich und für ein besseres Verständnis des Inneren Aufbaus der Nukleonen ist die Baryonenspektroskopie ein wichtiges Werkzeug. Im ...

Die Theorie der starken Wechselwirkung ist im Energiebereich ihrer Bindungszustände, der Mesonen und Baryonen, nicht störungstheoretisch behandelbar. Durch die Untersuchung des Anregungsspektrums der Baryonen kann ein ......

In the course of my PhD work, I have been involved in the development and the construction of the Tagging System for the BGO-OD experiment at the ELSA accelerators of the University of Bonn.
BGO-OD is a fixed target ...

Hadrons are composite particles which experience a mutual, non-fundamental interaction, i.e. the same force responsible for keeping protons and neutrons bound together within the atomic nucleus. This hadronic interaction ...
