| When physics meets machine learning: new tools for a new era |
| Speaker: | Luigi Favaro (UC Louvain) |
| Abstract: | The interplay between physics and machine learning is opening a new era in how we simulate and analyze collider events. In this talk, I will show how machine learning is affecting the collider simulation chain by replacing expensive components with precise surrogate models that maintain accuracy across the full phase space. Beyond speed, the most powerful gains come from integrating physical knowledge directly into model architectures. Whether through physics-motivated parameterizations or by directly embedding known symmetries into the architecture, we obtain models that are more robust, data-efficient, and physically consistent. Throughout, I will argue that physicists bring irreplaceable expertise to this effort, and that the dialogue between domain knowledge and modern machine learning is what will ultimately maximize the discovery potential of experiments like the LHC. |

| Dijkgraaf-Witten TQFT with defects |
| Speaker: | Catherine Meusburger (FAU Erlangen) |
| Abstract: | We give a gauge theoretical construction of 3d Dijkgraaf-Witten TQFT with defects. It does not require choices of triangulations, allows an easy computation of examples and can be applied to defects in Kitaev's quantum double model. This is joint work with João Faria Martins, arXiv: 2410.18049 |

| Radioactive Molecules - New Probes for New Physics |
| Speaker: | Dr Stephan Malbrunot-Ettenauer (TRIUMF, Vancouver & Dept. of Physics, University of Toronto, Canada) |
| Abstract: | Molecules, in which one of its constituting atoms contain a short-lived radioactive nuclide, were recently introduced as intriguing objects of research. These radioactive molecules can be tailored to maximize the sensitivity to new physics beyond the Standard Model of particle
physics. For example, when incorporating octuple-deformed âpear-shapedâ radionuclides into polar molecules, one obtains captivating probes for molecular electric dipole moments (EDMs), with unparalleled sensitivity to phenomena associated with time-reversal-symmetry breaking inside the atomic nucleus. Uncovering novel sources of time-reversal violation has the potential to resolve one of the most tantalizing puzzle in modern physics, i.e. why there is more matter than antimatter in the universe.
