High Energy Physics

High energy physics involves the study of the fundamental building blocks of nature at the shortest distances. These are the fundamental particles that are described by quantum fields such as the Higgs field found at CERN's Large Hadron Collider (LHC). Our group studies theories beyond the Standard Model of particle physics both from theoretical and phenomenological perspectives.

In this talk, I will give an overview of how to do field-level likelihood-free inference with galaxy catalogs.
More specifically, only using phase-space information, I will show how to convert galaxy catalogs into graphs.
I will explain how to use graph neural networks, associated with moment neural networks, to constrain Omega matter.
