24.05.24 From 13th to 17th may the workshop for Strange hadrons as precision tool for strongly interacting systems (SPICE) took place in Trento. “With 52 international participants and 39 keynote speakers, the conference offered a perfect platform to assess the present status of the field, to identify potential synergies within the community and to define experimental objectives for new cutting-edge research activities” Prof. Josef Pochodzalla, one of the organizers, resumes. To cover the field as broadly as possible a variety of topics were addressed during the five days workshop, including hypernuclei, exotic atoms, femtoscopy, extreme neutron rich nuclei, the kaon-nucleus interaction and the strangeness in neutron stars.
The workshop was supported by the EU Strong 2020 project and ECT*.
Francesca Bonaiti is receiving the 2024 DAAD prize for international students
Francesca Bonaiti from the group of Sonia Bacca stands out as one of the top physics PhD students at JGU. Consistently achieving exceptional results in her theoretical research, she has published several papers in peer-reviewed journals. Recognized for her strong potential, she also has collected several invitations to international conferences and has recently secured the prestigious 5-year FRIB theory fellow position in the USA.
Francesca Bonaiti's research lies in the field of theoretical nuclear physics. Employing complex computational tools, she studies the behaviour of atomic nuclei immersed in electric and magnetic fields, starting from the strong force binding protons and neutrons together in the nucleus. Her work, deepening our knowledge of nuclear structure, helps in advancing our understanding of the nature of neutron stars.
The consortium of Professor Maarten Boonekamp from Université Paris-Saclay as spokesperson and Professor Jens Erler and Professor Frank Maas of Johannes Gutenberg University Mainz has been awarded an ERC Advanced Grant for their project Zeptometry. This project aims to combine new precision measurements at the highest LHC energies at the European Organization for Nuclear Research CERN with challenging new precision measurements at very low energies with the upcoming MESA accelerator in Mainz in connection with the theory interpretation of the experimental results. The funding will be dedicated to the study of interactions between the Z boson and the fermions, i.e., the quarks and leptons constituting ordinary matter, to which end the upcoming experiment P2 at the Mainz electron accelerator MESA will be crucial.

The founding director of our Institute turns 100 today
28 Feb 2024
Herwig Schopper, a pioneer in experimental particle physics in Germany and Europe and the founding director of the Institute of Nuclear Physics at the Johannes Gutenberg University Mainz celebrates his 100th birthday today.
The "International Conference on Meson-Nucleon Physics and the Structure of the Nucleon (MENU 2023)" took place in the historic building of the Erbacher Hof in the old town of Mainz from October 16 to 20, 2023. More than 140 participants from 15 countries discussed their research results on topics in the field of hadron physics and related areas in 26 plenary and 77 parallel lectures sessions. Future developments in this field of research, such as the Electron-Ion-Collider in the USA and the Mainz Energy Recovering Accelerator MESA in Mainz, as well as new forward-looking developments in theory, also played a major role.
In addition to the lecture sessions, the program also included a visit to the Mainz Microtron (MAMI) on the campus of Johannes Gutenberg University followed by a poster session. In addition, Prof. Dr. Thomas Haberer, scientific-technical director of the Heidelberg Ion Beam Therapy Center at Heidelberg University Hospital, gave a public evening lecture on "Tumor Therapy at Particle Accelerators - From the Laboratory to Clinical Routine," illustrating how the tools of basic research can find application in people's everyday lives.
For financial support of the event, the organisers thank the European Physical Journal A (Hadrons and Nuclei) and the Helmholtz Institute Mainz.

The "25th European Conference on Few-Body Problems in Physics" took place this year on the campus of JGU Mainz. In 13 sessions over 5 days more than 150 scientists from all over the world discussed current issues in the fields of hadrons, (hyper-)nuclear physics, cold atoms and molecular physics. Ukrainian researchers were connected online, as they were unable to attend on site due to the war in Ukraine.
After years of development work, the new Pixel Vertex Detector (PXD2) was successfully installed in the international Belle-II experiment at the SuperKEKB electron-positron accelerator in Japan. Concettina Sfienti's group at the Institute of Nuclear Physics was also involved in the design and construction. Under Mainz leadership, real-time monitoring of data quality was implemented and key sections of the software controlling the PXD2 were programmed. In addition, sensor modules were tested at MAMI for their radiation hardness.
The special feature of the PXD2 is that, due to its very compact design, it can deliver 50,000 high-resolution images per second at a distance of only 1.4 centimeters from the collision point. From this, the exact decay location of short-lived particles, especially B mesons, can be determined very accurately and the decay products can be detected with high precision. In combination with the high collision rate at SuperKEKB, fundamental phenomena such as CP violation can thus be studied in high detail - with the goal of understanding the imbalance between matter and antimatter in the universe!
The new detector is scheduled to start taking data in early 2024.

From 26.06.23 to 30.06.23, this year's workshop of the "Proton Radius European Network" (PREN 2023) and the "Muonic Atom Spectroscopy Theory Initiative" (µASTI) took place in the premises of HIM at JGU Mainz. Over the five days, more than 50 scientists from more than a dozen countries discussed their research on the structure of nucleons and nuclei, as well as the search for New Physics, by confronting precise theory predictions with electron scattering experiments and spectroscopy of in part exotic atoms and molecules. "Overall, we had a very diverse program with many exciting discussions that motivate and inspire us to work even more closely on common issues in the future. We are already looking forward to the next event," summed up local organizers Franziska Hagelstein (Institute of Nuclear Physics) and Randolf Pohl (Institute of Physics).
