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.

We present the Einstein-Maxwell-Klein-Gordon system in hyperboloidal slices, a recent formulation for extracting signals at future null infinity. As far as we know, this is the first time this setup is evolved with a common formulation like BSSN/Z4. Using hyperboloidal slices, contrary to other recent methods like Cauchy-Characteristic Matching, we can continuously reach future null infinity.
