The detector of the PANDA experiment at FAIR is optimized for hadron spectroscopy especially in the charm sector. Main topics of the PANDA physics program are the search for new and predicted states and the precise measurement of the line shape of new and already discovered resonances, e.g. the X(3872).

The description of nuclei starting from the constituent nucleons and the realistic interactions among them has been a long-standing goal in nuclear physics. In addition to the complex nature of nuclear forces with two-nucleon, three-nucleon and possibly even four-nucleon components, one faces the quantum-mechanical many-nucleon problem governed by an interplay between bound and continuum states.

The PANDA detector requires excellent particle identification (PID) for the full solid angle and a wide momentum range. In the barrel region of the detector the hadron PID will be performed by a DIRC counter. The successful BABAR DIRC inspired the baseline design of the PANDA Barrel DIRC, which was further advanced by such modifications as fast photon timing and focusing optics. Narrow long radiat ...

Owing to the recent advances in heavy-ion accelerator facilities as well as in detection techniques, new possibilities arise to study the electronic structure of simple atomic systems in strong Coulomb fields. Relativistic, quantum electrodynamics, and even nuclear effects, which are difficult to isolate in neutral atoms, often become enhanced in high-Z, few-electron ions. In order to improve our ... More

Collisions of highly charged ions allow to study relativistic and quantum electrodynamic effects. If the total charge of the colliding nuclei is larger than Zc = 173, the ground state of the combined quasimolecular system should dive into the negative-energy Dirac continuum. Investigation of the processes accompanying such collisions can gain insight into the detection of the diving phenomenon. R ... More

The main physics motivation of PANDA is to explore the non-perturbative regime of QCD and to study hadronic states. In this context, here is a possibility to include hyperon studies in the PANDA physics program. Hyperons travel a large distance before they decay into other particles. In order to increase the acceptance to measure these particles, there is a concept to include an additional “Lamb ... More
