Hadrons and Nuclei as Discovery Tools: New Collaborative Research Centre Granted

The German Research Foundation (DFG) approved the establishment of the CRC 1660 "Hadrons and Nuclei as Discovery Tools" at Johannes Gutenberg Unversity. This newly granted Collaborative Research Centre will allow for an interdisciplinary approach to the search of new physics phenomena, and it will significantly sharpen our understanding of strong interaction processes.
By bringing together the fields of atomic, nuclear, and hadron physics, this project holds a unique discovery potential along three main research pillars.

In the first pillar, experiments at low energies and high intensities are used to search for new particles (e.g. dark matter particles) and interactions beyond the SM, and the results are interpreted using lattice QCD. The second pillar investigates the interface between hadron and nuclear physics through spectrometry experiments, electron and photon scattering experiments and high-precision calculations that will improve the interpretation of neutrino experiments and the description of muonic atoms. The third pillar focuses on the exploration of nuclear astrophysics and multi-messenger astronomy with a new generation of high-precision experiments in low-energy nuclear physics combined with state-of-the-art theoretical calculations using effective field theories.

The very broad combined expertise in atomic, nuclear and hadronic physics within this CRC will allow for a significant impact on all the above research avenues simultaneously. The outstanding opportunities enabled by the new local MESA accelerator, which is coming online, as well as at the MAMI (Mainz), BESIII (China), and PSI (Switzerland) facilities, combined with the very strong interplay between the theoretical and experimental groups, will foster unique physics and methodological connections between the different research fields and create a favourable environment for discoveries.

Stadtradeln

Over the next three weeks (03.06. to 23.06.2024), every kilometre travelled by bike counts!

AG Sfienti supports the university's efforts for this year's Stadtradeln campaign with a team of seven to promote the use of bicycles in everyday life. Check out our new logo for this event!

Bachelor’s Degree for Justin Letschert

Justin Letschert successfully completed his bachelor thesis “Untersuchung der Strahlenhärte der Belle II Pixeldetektor-Spannungsversorgung an MAMI” as well as his final exam and was awarded the title of Bachelor of Science (B.Sc.).

During his time at AG Sfienti, he investigated the radiation hardness of the Belle II Pixel Detector power supply at MAMI.

Congratulations!

The Belle II experiment resumes operations

After approximately 18 months, the SuperKEKB electron-positron collider was ready to restart its work. The long shutdown (LS1) provided ample time to upgrade the collider and the Belle II detector. Since 20 February Belle II is recording collision data again.

Björn Spruck from AG Sfienti is currently in Japan making sure the new Pixel Vertex Detector (PXD2), which was installed last year during LS1, is operational for successful data collection.

AG Sfienti in Bormio

AG Sfienti is currently in Bormio, Italy, participating in the International Winter Meeting on Nuclear Physics
(22-26 January 2024).

It is the 60th jubilee of this long-standing conference, which has been bringing together researchers and students from various fields of subatomic physics for decades.

A great reason to celebrate!

There are overview talks on the on the various fields covered by the conference

  • Nuclear Astrophysics and Nuclear Structure
  • Heavy Ion Physics
  • Hadron Physics
  • Particle Physics
  • Applied Nuclear Physics
  • Detectors and Future Projects

Special attention is also given to their interplay with and impact on other major fields of fundamental physics.

Prof. Dr. Concettina Sfienti has acted as an organizer and co-chair of this meeting for years.

Academy Prize of Rhineland-Palatinate for Prof. Dr. Concettina Sfienti

Prof. Dr. Concettina Sfienti was awarded the Academy Prize of Rhineland-Palatinate to honour her outstanding and exemplary achievements in teaching and research.

The award ceremony took place at the Akademie der Wissenschaften und der Literatur Mainz
on 30 November 2023.

The welcome addresses by Prof. Dr.-Ing. Reiner Anderl, President of the Akademie der Wissenschaften und der Literatur Mainz and Clemens Hoch, Minister of Science and Health of the Federal State of Rhineland-Palatinate were followed by a laudation by Prof. Dr. Margret Wintermantel, Chairperson of the jury for the Academy Prize.

The award winner, Prof. Sfienti, contributed to the evening with her talk on "Sternenstaub im Bauch: Kosmische Rezepte für Erdlinge" giving an overview of the origin of the elements found in the universe.

Music by Zih-En Wei (violoncello) and André Dolabella (piano) provided a festive backdrop to the evening.

It’s beam time again!

Our next transverse asymmetry beam time at A1 has just started (07. to 20. November). We will take data with the precious 208Pb target this time!

And we are also testing the radiation tolerance of an improved version of the Belle II PXD power supply.

PXD2 installed in Belle-II Experiment

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. Under our 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.
