Yesterday, the annual meeting of the German committee for hadrons and nuclear physics started. There will be reports on all major related experiments Germany is involved in and what the plans for the future are.

On Nov. 26, I will give my inaugural lecture at the @jlugiessen.bsky.social on the topic of how to calculate exotic hadrons with functional methods.

We extended functional calculations of mesons up to J=5. In the channels, for which the employed rainbow-ladder setup is known to work well, we observe Regge trajectories. We find that the "potentials" corresponding to the used interactions contain linear rising sections. arxiv.org/abs/2510.27423

Submitted my contribution to the forthcoming Encyclopedia of Particle Physics to arXiv: arxiv.org/abs/2510.18960 I hope this "Beginner's guide to functional methods" will be helpful to many starting in the field and provide useful information to those just wanting to see what funMethods are about.

Last week was also when Jonas Wessely started his new job here in Giessen. He will work in my DFG grant on resonances in QCD using functional methods. Welcome, Jonas!

Last week, we kicked off the autumn season with a one-day group meeting. Reports on progress and future plans on the agenda, but also talks by former students about their experiences in industry: finance, consulting, entrepreneurship, programming, medical sector.

After a very interesting BESIII meeting where I got some insight into how experimental collaborations work, I could take a quick tour through Münster. A very charming city with many houses that look old and original, though I learned many of them were rebuilt like that after WWII.

Off to the BESIII Europe meeting to discuss the search for glueballs. Many promising recent results from BESIII on this. How can theory help? Are there any more interesting analyses to be expected?

This week in Oberwölz, organizing the workshop 'Real-Time and Non-Equilibrium Quantum Field Theory' funded, among others, by the Heraeus foundation. Great talks, great views!

Summer term is over. Is it? No, just lectures. There are still exams to write. Hope the students prepare well. This time, I have to oversee a combined exam on electrodynamics and thermodynamics 💡🌡️. 3 hours of fun with fields and state variables.

Workshop going on. Interesting talks and many discussions, both moderated in plenum and spontaneously in small groups.

On my way to Trento for a workshop on QCD in Euclidean and Minkowski space-time. Fun fact: There was a bug (?) in the google weather forecast lowering the predicted temperature to sub 10°C. Around Trento, weather is fine, other forecasts are also ok. indico.ectstar.eu/event/235

Open Campus Day 2025 an der @jlugiessen.bsky.social: Für alle, die wissen wollen, was es an der JLU für Studierende gibt, von Studiengängen über Unterstützungsmöglichkeiten bis zu Hochschulsport. youtube.com/shorts/P4Rd-... Mehr Infos: www.uni-giessen.de/de/studium/a...

I am in Budapest for the #ACHT2025 meeting. Topics range from hadrons to neutron stars to neutrino oscillations.

Skype will retire in May 2025. I used it since my early days as a student and have built a network of contacts. As of now, I am not sure how to replace it. What recommendable Skype alternatives are there? MS suggests Teams, but that program stayed behind my expectations up to now.

Talk on quantum teleportation by Christian Fischer in the public lecture series 'Physik im Blick' at JLU Giessen. Alice and Bob are well known in this context, but who or what are the Brezchen? We find out now...

This week, 'Physik im Blick' continues with quantum teleportation and an overview of the physics Nobel prize 2024. Come on Saturday and meet Alice and Bob (live act 😆). www.uni-giessen.de/de/fbz/fb07/...

Saturday and a full lecture hall? Yes, today is the first lecture of "Physik im Blick" at JLU Giessen, a series of lectures for high school students. This year's theme: quantum physics. Today, it's about the photoelectric effect. www.uni-giessen.de/de/fbz/fb07/...

If you are interested to work on hadronic resonances and decays at JLU Giessen, there is a job opening for a Postdoc position in our group: inspirehep.net/jobs/2869870
