Calendar of Physics Talks Vienna
| MadNIS and the Road to MadGraph7 |
| Speaker: | Ramon Winterhalder (Universita degli Studi di Milano) |
| Abstract: | High-precision simulations based on first principles are a cornerstone of any modern physics research. For instance, as we approach the HL-LHC era, there is an ever-increasing demand for both accuracy and speed in simulations. Modern Machine Learning (ML) techniques are emerging as a beacon of hope, potentially diminishing the limitations of current methodologies and opening doors to uncharted territory in the parameter space. In this presentation, I will first explain the basic principles of machine learning and highlight current LHC event generation methodologies and their bottlenecks. Afterwards, I will delve into the MadNIS framework and illustrate how modern ML techniques can alleviate these limitations. In particular, I will present recent advancements in neural importance sampling, summarize the developments for differentiable event generators, and outline the future of MadGraph. |

| The Strong Interaction at 50 Years: Less Puzzling, More Rich, and Still Mysterious |
| Speaker: | Iain Stewart (MIT) |
| Abstract: | The strong interaction is described by a remarkable theory called Quantum Chromodynamics (QCD), a quantum field theory that is fully consistent at all distance scales and that gives rise to interesting emergent phenomena. It plays a crucial role in a variety of important physical processes, from binding together quarks and gluons in the proton, to the evolution of a hot-plasma of matter in the early universe, to producing streams of collimated particles called jets in high energy collisions. In this talk I will review what we have learned about QCD and its phenomena in the fifty years since its inception, as well as discussing the important role that control of QCD effects have on measuring the fundamental parameters of the standard model of particle and nuclear physics. To highlight the mysteries of QCD that remain unsolved, I will describe a top-10 list of important open questions. |
