Welcome to the Institute for Nuclear Physics

The Mainzer Microtron MAMI, an electron accelerator for energies of up to 1,6 GeV, is the core of experimental investigations. Additionally, scientists at the Institute of Nuclear Physics are working on the theoretical description and interpretation of the experimental results and of external experiments in, for example, Beijing (IHEP), Darmstadt (GSI) and Geneva (CERN).

We congratulate Ms. Bianca Savino on completing her dissertation titled

"Development of Λ baryons reconstruction and its application to the search for a stable hexaquark at Belle II"

This thesis focuses on the search for a hypothetical particle composed of six quarks in the context of the particle physics experiment Belle II in Japan. The possible existence of such a state would help us to better understand the behaviour of matter under extreme circumstances.
The work can be divided into two main parts: the optimization of the Belle II software deployed in the reconstruction of tracks originating far from the main interaction point; and the subsequent sensitivity study for the search for the six-quark state, heavily relying on such tracks.

Last Friday afternoon, the guests of the Mainz Science Tram experienced an entertaining and informative ride. Various scientists from Mainz introduced them to very different fields of research on the tour through Mainz. Professor Achim Denig from the Institute of Nuclear Physics was also on board with his lecture "Quarks & Co - The fabulous world of the smallest particles". With a wink, he pointed out to the audience at the beginning that the lecture was of course not about (food) quark, but about the building blocks of which all matter, whether humans, galaxies or food quark, is composed. In the past decades, nuclear and particle physics have succeeded in identifying the basic building blocks of matter - the so-called elementary particles - and in describing their interaction with each other in the Standard Model of particle physics. These elementary particles include quarks, which exist in six types and form the basis for protons and neutrons.

The Institute of Nuclear Physics is taking part in the Mainz Science Week! During a guided tour on 17.09.22 you will have the opportunity to experience the Mainz Microtron MAMI, an electron accelerator, on the JGU campus. We will show you the path the electrons take through the accelerator from their generation to the various experiments, explain the principle of a racetrack microtron and give you an insight into the experiments we use for our research.

Join us 11m deep underground and experience impressive technology and exciting physics!

Information on registration and organisational details can be found on the Mainz Science Week website. The number of participants is limited.

To perform research at the frontier of knowledge, it is necessary to have excellent scientists and an extensive technical infrastructure with well-trained specialists. For this reason, the Institute for Nuclear Physics has, for many years, provided training for young people in technical and mechanical professions, such as IT specialists.

This year, Jonas Bissantz and Jonas Steiner successfully completed their training as IT specialists, focusing on system integration at the Institute for Nuclear Physics. Mr. Bissantz’s project topic concerned the "Integration of an IP-KVM Solution for Remote Maintenance of Servers and Workstation Computers", an inexpensive "Keyboard-Video-Mouse" hardware based on RaspberryPis. In his project, Mr. Steiner dealt with the "Re-implementation of a Self-Hosted Warehouse Management System (WMS) on Existing Hardware".

We congratulate them both on the successful completion of their training and wish them all the best for their future careers!

From July 25th to August 12th, 2022, the TALENT School on “Effective Field Theories in Light Nuclei: From Structure to Reactions” took place in Mainz. Sponsored by MITP, this event was organized by Prof. Pierre Capel and Prof. Sonia Bacca from the Institute of Nuclear Physics. Lectures were held in the conference room at the Helmholtz Institute Mainz.
32 students from 10 different countries (Belgium, Brazil, Canada, France, Germany, Iran, Israel, Italy, Spain, and USA) came together to learn the most modern techniques for tackling few-body sys-tems in nuclear physics. Students also had the opportunity to visit the MAMI facility and see the MESA construction site. After being galvanized by this experience, they are going back to their home institutions with more knowledge, more professional connections and new friends.
We wish them all the best and hope to see them again in Mainz in the near future!

We congratulate Dr. Matthias Heller on completing his dissertation titled

"Radiative corrections to Compton processes on the proton and to the Drell-Yan process"

In this thesis, Matthias Heller calculated radiative corrections to two fundamental processes of the Standard Model: the Compton process on the proton and the Drell-Yan process. Experimentally, the Compton process is the most important tool to study structure functions and other intrinsic properties of the proton. The Drell-Yan process on the other hand, is one of the most basic processes measured at the LHC at CERN and has a long history for probing the theory of strong interactions.

We congratulate Dr. Daniel Alberto Stanischesk Molnar on completing his dissertation titled

"The Role of Exotic Mesons and Final State Interactions in e+e− Collisions"

In recent years, a plethora of new resonances has been discovered in the charmonium region, which cannot be interpreted in a simple quark model picture as states consisting of a charm quark and an anti-charm quark. A study of the reaction dynamics through which such states are produced is crucial to understanding the intrinsic properties of these exotic resonances and for shedding light on their nature. Daniel Molnar used a state-of-the-art approach to investigate three reactions in which charged exotic states were observed by the BESIII Collaboration in electron-positron collisions, achieved a physical description of the current experimental data, and furthermore made predictions to be tested in future experiments.

The ATLAS detector more powerful than ever – with major contributions from Mainz University

On July 5th, protons are expected once again colliding with each other at speeds close to that of light in the Large Hadron Collider (LHC) at CERN, also giving physicists of the PRISMA+ Cluster of Excellence of Johannes Gutenberg University Mainz (JGU) something to celebrate. Over the last three years, they have made important contributions to the upgrade of the ATLAS detector, ensuring that it can cope with even greater volumes of data during Run 3 of the largest particle accelerator in the world. As a result the researchers hope to gain new and more extensive insights into the universe of the very smallest particles. ...

New record: Mainz University can spend EUR 3 million in the Erasmus+ student mobility program in the 2022/2023 academic year / Bilateral agreements with more than 400 partner universities throughout Europe

The European Erasmus+ program is celebrating its 35th anniversary. Johannes Gutenberg University Mainz (JGU) has been involved with the European Union's best-known education program and its unique success story from the very beginning in 1987: Erasmus+ has supported around 12 million European citizens in experiencing Erasmus mobility so far, including almost one million Germans in the field of higher education. Mainz University is deeply committed to the Erasmus+ program. In 2019, JGU was among the first universities to succeed in the European Universities Initiative established by Erasmus. Together with its partners in now eight European countries, Mainz University is building the European University FORTHEM Alliance. Measured in terms of the total number of placements, JGU is also one of the most active German universities in the field of Erasmus+ mobility. In fact, Mainz University has even received a number of awards for its outstanding involvement, including the Erasmus E-Quality seal of approval...
