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.

Seminars
In this seminar, we study and present constraints for two cosmological models based on non-metric theories of gravity, referred to as f(Q) gravity, using both current datasets and forecast Standard Siren events.
The first model is the most general f(Q) model that replicates a ΛCDM background, with deviatio
