\begin{abstract}A systematic description of low-energy observables in light nuclei is presented. The effective field theory formalism without pions is extended to:\begin{itemize}\itemindent=2cm\item predictions with next-to-leading-order accuracy for\item[] the 4-helium binding energy...
This thesis reports on the first helicity asymmetry measurement for single neutral pion photoproduction using the CLAS detector in Hall B at the Thomas Jefferson National Accelerator Facility (JLab).This measurement used longitudinally polarized protons and circularly polarized photons at...
Strangeness channels are important in the experimental search for missing baryon resonances. Phenomenological reaction models for the extraction of resonance parameters, such as coupled-channels analyses, require data for many observables, in different channels, and on different targets. The...
Deuteron photodisintegration is a benchmark process for the investigation of the role of quarks and gluons in nuclei. Existing theoretical models of this process describe the available cross sections with the same degree of success. Therefore, spin-dependent observables are crucial for a better...
