Status of the 2nd FP and towards a third one

Due to the corona pandemie, the review of the application for the 3rd FP in February was cancelled. The second FP was extended until the end of 2020. The review for FP3 will take place in September (for a funding period from 1.1.2021 to 30.6.2024).
The achievements of the second FP and the outlook for the third FP are documented in form of posters, see

Four day particle physics academy and training program for high school teachers

In 2019 the CRC offered for the fourth time its four day particle physics academy for high school students (with 25 participants from 10th to 13th grade) as well as a one day  training program for high school teachers (23 participants) on the same topic.  Venue for the former was as in all previous years the Science College Overbach in Jülich, which provides an ideal environment since housing, lab and lecture hall are all on site.
After having provided already a teachers training program in Jülich, Munich and Bonn, this year it was offered in Bochum. Both programs contained overview lectures as well as lectures on current issues in nuclear and particle physics always with special emphasis on theoretical aspects which wasvery much appreciated by the participants. In addition, we presented demonstration experiments to illustrate the theoretical concepts.
In the course of the particle physics academy we also offered three projects to
the students: In first one they got a chance to get in touch with the fundamentals of quantum mechanics, in the second they learned how
to simulate numerically the trajectory of  Mercury and in the third they discussed requirements of a scientific approach to philosophical issues like the anthropic principle.
For both programs the feedback provided by the participants was extremely positive.




The weak decay parameter of the Lambda hyperon revisited

The weak decay parameter of the Lambda hyperon is an important quantity for the extraction of polarization observables in various experiments.
The value endorsed by the PDG and accepted and used for over 40 years is 0.642(13). However, last year the BESIII Collaboration reported evidence that it could be almost 20% larger, namely 0.750(9)(4).
Now a group of physicists including  CRC members from projects A.1 and B.11 has made an independent estimate for that quantity, using an extensive set of polarization data measured in kaon photoproduction and utilizing constraints set by spin algebra. The value found in this analysis  is 0.721(6)(5) and thus confirms the BESIII conjecture that the decay parameter is significantly larger than the previously accepted value.

Performances of Bonn Particle Physics Show in 2018

On March 16th and 17th, 2018, we performed the Bonn Particle Physics Show in  the Wolfgang-Paul Lecture Hall of Bonn University. Both performances were sold out (2x 550). On March 19th, upon invitation of Prof. Matthias Neubert, the director of the MITP (Mainz Institute of Theoretical Physics), we performed the Particle Physics Show in the Mainz Staatstheater (see photo). This performance was also sold out. It was an amazing experience to perform in such a professional theater.

From Sept 17th-21st, we were guests of Professors Gui Rebelo and Gustavo Branco at Instituto Superior Tecnico in Lisbon. We performed the Particle Physics Show in the main physics lecture hall. Guests included the president of Tecnico, Professor Arlindo Oliveira, as well as the president of the Portugese Physical Society, Prof. Maria Teresa Peña. In Lisbon we also held a workshop in public presentation of science for the local particle physics students.
This trip was partially supported by EU-COST Action CA15108.

From Sept 21st-25th, we were guests of the IFT Madrid (Institut of Theoretical Physics). We performed the show three times in the Caixa Forum, a wonderful museum in downtown Madrid. Our host was the director of the IFT, Prof. Angel Uranga. Again all three shows were sold out (3x 420).

CRC Workshop - Amplitudes for Three-Body Final States

Three-body hadronic decays of heavy mesons and the tau lepton are important tools for studying both meson-meson strong interactions and weak dynamics in a wide energy range, from pi-pi threshold up to the B-meson mass around 5 GeV. With the recent increase of experimental precision achieved by LHCb, BESIII, COMPASS, and in the near future by the Belle II experiment, data require more refined theory-based amplitudes in order to interpret the underlying dynamics. In this context, our workshop will join theorists and experimentalists in order to discuss different issues concerning final-state interactions in amplitude analyses in three-body decays of hadrons and leptons. The format of the workshop is meant to offer a fruitful environment for discussions and exchanging issues and developments among experimentalists and theorists. We want to favor the interplay between both sides in order to arrive at productive conclusions.

For more information, details and registration see the webpage.


Review on ''Hadronic Molecules'' published

Six PIs from Beijing, Bonn and Jülich published a review article on the
topic of ``Hadronic Molecules'' in Reviews of Modern Physics. This article
gives a detailed account of the theory of such exotic states and its
application to the hadron spectrum, as investigated within this CRC
and at many other places world-wide. The close analogies to
few-nucleon systems are also discussed, showing once more how the
quest for understanding the emergence of structure in QCD ties
together hadron and nuclear physics. It is also a nice showcase of
the intense and fruitful sino-german collaboration. For more details, see

Physikshow (Physics Show) in China

From March 15th to March 23rd, 2016 Prof. Herbert Dreiner and the Bonn Physikshow travelled to Beijing, to train local Chinese physics students in show physics. The Bonn University team consisted of seven physics students (Jana Bürgers, Timo Heepenstrick, Katharina Hortmanns, Christian Jost, Johannes Müllers, Steffen Schaepe, Laura Weber) as well as Michael Kortmann, the technician responsible for the extensive demonstration experiment collection in Bonn. In a short 5 day workshop we trained fifteen Chinese physics students from the Institut for Theoretical Physics at the Chinese Academy of Sciences as well as from Peking University (PKU) to put on their own show in Chinese. The workshop ended in a  public show at PKU put on by the local students in Chinese and using local equipment from the PKU collection. About 150 Chinese high school students attended the show, which was a huge succes.

In a blog post on the British newspaper Guardian’s website, Prof. Dreiner tells the story.
