Hadron and particle physics aim at a quantitative understanding of the fundamental building blocks of matter, which are currently described by the Standard Model. Our research focuses on precision tests of the Standard Model at the local electron accelerators MAMI and MESA, as well as at external facilities in Darmstadt (GSI/FAIR) and Beijing, China (BESIII experiment).

These measurements address key open questions of the Standard Model: Can effects of physics beyond the Standard Model be resolved in precision observables such as the anomalous magnetic moment of the muon? Could dark matter consist of relatively light particles accessible in our experiments? What is the intrinsic nature of exotic forms of matter? And can we fully understand conventional states of matter such as the proton?

The group of Achim Denig is involved in the development of detector components for these unique experiments and works on physics simulations and data analysis tools to address these questions. Please contact us if you have further questions.

BESIII is the main detector at the tau-charm factory BEPC-II, which is an e+e- collider operating in the energy range between roughly 2 and 5 GeV. Our group is mainly involved in the data analysis, but has also provided a hardware contribution to the BESIII detector, namely the cZDD detector.

MAGIX is a spectrometer setup at the new accelerator MESA, where for the first time the innovative accelerator concept of energy-recovery will be combined with an internal gas target. This opens the avenue for precision experiments in the field of nuclear, hadron and particle physics.
DarkMESA a beam dump experiment at MESA, which will exploit the extremely high beam intensities of the accelerator to search for Light Dark Matter particles.

The PANDA experiment is a planned particle physics experiment at the Facility for Antiproton and Ion Research in Darmstadt. PANDA will use proton–antiproton annihilation to study strong interaction physics at medium energies. Our group is involved in the development of the luminosity detector, which will also be used for the KOALA experiment at GSI.
