      Learning Particle Physics: From Simulation to Inference with Neural Networks

      Neural networks are transforming the way we simulate and analyze data in particle physics. Modern experiments produce enormous amounts of data, and understanding them requires complex and computationally expensive simulations. Machine learning offers new ways to make these steps faster, more efficient, and even invertible.

      Neural networks can be used throughout the full simulation chain: from the interpolation of interaction cross sections, via the generation of artificial particle events, to modeling the detector response, machine learning enables high-precision predictions. In the inverse direction, neural networks can reconstruct the underlying physical processes from the measured high-dimensional data. Along the way, we focus on incorporating physics knowledge—such as exact and approximate symmetries—into network architectures and training objectives, alongside the precise quantification of uncertainties to ensure physically meaningful predictions.

      Anja Butter is a researcher at LPNHE (CNRS) in Paris, where she has held a permanent position since 2022. She obtained her PhD in theoretical physics from Heidelberg University, working on global analyses in effective field theories and dark matter. She then spent one year in industry at NEC Laboratories conducting research in machine learning, followed by a postdoctoral fellowship at the interface of machine learning and particle physics. Her current research focuses on machine learning methods for particle-physics simulations and statistical inference.
