Am Institut f\u00fcr Kernphysik forschen wir im Bereich der Hadronen- und Kernphysik<\/a>, der Beschleunigerphysik<\/a> sowie der Astroteilchenphysik<\/a>. Hierzu organisieren sich unsere Wissenschaftlerinnen und Wissenschaftler der experimentellen Arbeitsgruppen in vier Kollaborationen, die aktuell die beiden Experimente A1 und A2 am Beschleuniger MAMI <\/a>betreiben und die Experimente MAGIX und P2 am Beschleuniger MESA<\/a> aufbauen. <\/p>\n\n\n\n

Thanks to our broad, complementary experimental and theoretical capabilities and the high precision of our results, we are regularly successful in the competition for funding<\/a>: The CRC 1660<\/a> “Hadrons and Nuclei as Discovery Tools” was launched in October 2024. Unsere Forschungsthemen liefern zudem einen substantiellen Beitrag zum durch die Exzelleninitiative des Bundes und der L\u00e4nder gef\u00f6rderten Exzellenzclusters PRISMA+<\/a>. <\/p>\n\n\n\n

Our various working groups are also involved in other large-scale experiments outside Mainz, for example by developing detectors or analyzing measurement data with special algorithms. <\/p>\n\n\n\n \n\n \n<\/jgu-base-logogriditem>\n\n\n\n \n<\/jgu-base-logogriditem>\n\n\n\n \n<\/jgu-base-logogriditem>\n\n\n\n \n<\/jgu-base-logogriditem>\n\n\n\n \n<\/jgu-base-logogriditem>\n\n\n<\/jgu-base-logogrid>\n\n\n\n

We also have a close connection to the neighboring Helmholtz Institute Mainz (HIM)<\/a> – an institutional cooperation between the Johannes Gutenberg University Mainz and the GSI Helmholtz Center for Heavy Ion Research in Darmstadt.<\/p>\n<\/div>\n\n\n\n

The theory group investigates the strong interaction at low and medium energies. Its activities focus on the theoretical interpretation of experiments at MAMI, MESA and other accelerator facilities. Analytical methods such as effective field theories and dispersion theory as well as numerical simulations of the nuclear structure and quantum chromodynamics on the lattice are used for this purpose.<\/p>\n<\/div>\n\n\n\n
