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.

Greybody factors are frequency dependent quantities that measure the deviation from the perfect black body spectrum of Hawking radiation, and they provide us with valuable information about the near horizon structure of black holes. In
addition, when black holes are perturbed the geometry of spacetime undergoes dumbed oscillations.
