Abstract: Axion and axion-like particles appear ubiquitously in many beyond the standard model scenarios. In particular, the quantum chromodynamics (QCD) axion provides an interesting solution to the strong CP problem and can be a dark matter candidate in the present universe. If such an axion is dark matter, nuclear quantities, such as nucleon mass, might oscillate in time due to the interaction between the axion dark matter and the gluon field. I will discuss some of the experimental signatures of axion…

Abstract: In this talk I want to explain how Calabi-Yau geometries enter in Feynman integral computations. For this I will first give an introduction to Calabi-Yaus explaining the most relevant concepts in the context of Feynman integrals. Then I will give several examples of Feynman integrals corresponding to certain Calabi-Yau geometries. We will see that the properties of Calabi-Yaus will give us not only the appropriate functions the Feynman integrals evaluate to but also insights to find boundary…

Abstract: A workshop for an interdisciplinary exchange for accelerating developments of machine learning techniques in Lattice QCD with experts in Machine learning, Lattice QCD, and other related fields. This is a Covid safe workshop: FFP2 masks will be required. Please remember to bring with you FFP2 masks

Abstract: The EAS starts a new and unique workshop series, funded by the Wilhelm and Else Heraeus foundation, the HERA workshops. This workshop series will provide an environment where early career scientists are trained to interact, design research projects, develop a broad perspective and start international collaborations. The first workshop in this series will take place in the week of February 27th - March 3rd 2023 at the Max-Planck-Institute for Extraterrestrial Physics in Garching, near Munich,…

Abstract: CN-2 meeting with the idea that all researchers that are working on CN-2 related projects meet each other and to get to know the different research-projects. There will be multiple slots for 20 min (15+5) presentations. The presentations should be aimed at a non-expert audience composed of astrophysicists, biophysicicsts and chemists. If you would like to contribute a presentation, please provide the title in the registration from. The deadline for submitting contributions is February 17. …

Abstract: Line-Intensity mapping (LIM) is a novel technique to map cosmological volumes which allows to access unexplored regimes and unique cosmological and astrophysical information. This invaluable potential comes along with observational and theoretical challenges that will need to be addressed to fulfill the promise of LIM. With the first measurements already coming around, it is crucial to reassess the current status of LIM and the roadmap for the forthcoming years. The workshop “Present…
