Nuclear Reactions

In the last two decades, new unpredicted charmonium-like states with extraordinary characteristics have been observed experimentally. These states also known as the XYZ states, e.g., the Y(4260) or the X(3872), are mostly interpreted as QCD allowed exotic hadrons. [...]

The knockout of nucleons from nuclei is a powerful tool to investigate nuclear structure. In particular, the knockout of nucleons at energies above 200 MeV/nucleon from a hydrogen target, so called quasi free scattering, is believed to be a clean probe for nuclear structure and has led to several recent experimental programs and theoretical developments.
