Speakers: Vladimir Shiltev I will discuss key accelerator and beam physics developments that have advanced nuclear and high-energy physics, highlighting their relevance to major future projects such as the Electron-Ion Collider (EIC), Future Circular Collider (FCC-ee, a Higgs Factory at CERN), and the Muon Collider. I will first focus on electron lenses (e-lenses) for beam-beam ... Read more

Speakers: Chris Gordon (University of Canterbury) If QCD axion dark matter formed post-inflation, axion miniclusters emerged from isocurvature fluctuations and later merged hierarchically into minihalos. These minihalos, potentially disrupted by stellar encounters in the Milky Way, affect axion detectability. We extend prior analyses by more accurately incorporating multiple stellar encounters and dynamical relaxation timescales, simulating ... Read more

Speakers: Xiaochuan Lu (University of California, San Diego) Effective Field Theories (EFTs) have wide reaching applications in particle physics of and beyond the Standard Model (BSM). They also serve as the foundation for our modern understanding of renormalization in Quantum Field Theories. In this talk, I will discuss a few crucial aspects of EFTs, including ... Read more

Speakers: Brian Henning (Kavli Institute for Theoretical Physics/UCSB) High-energy physics experiments measure distributions of relativistic events across phase space, yet traditionally phase space has served merely as a calculational backdrop. In this seminar, I propose a paradigm shift: viewing phase space as a dynamic, geometric entity deeply entwined with the underlying physics. By treating phase ... Read more
