We present measurements of exclusive $\ensuremath \pi^{+,0}$ and $ \eta$ production in pp reactions at 1.25GeV and 2.2GeV beam kinetic energy in hadron and dielectron channels. In the case of $ \pi^{+}_{}$ and $ \pi^{0}_{}$ , high-statistics invariant-mass and angular distributions are …

To study fundamental questions of hadron and nuclear physics in interactions of antiprotons with nucleons and nuclei, the universal PANDA detector will be built. Gluonic excitations, the physics of strange and charm quarks and nucleon structure studies will be performed with unprecedented …

The photoproduction of $\ensuremath{\omega}$ mesons off protons has been studied at the Bonn ELSA accelerator from threshold to ${E}_{\ensuremath{\gamma}}=1700\text{ }\text{ }\mathrm{MeV}$. Linearly polarized beams were produced via coherent bremsstrahlung. Large photon asymmetries in excess of 50% were obtained. For the first time …
