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.

I will explore the idea of connecting the dark matter sector with a sector of the Standard Model (SM), namely the neutrino sector. To do this, I consider the extension of the SM with right-handed (gauge singlet) neutrinos, which will lead to a type-I seesaw mechanism. Then I also add a fermion (another gauge singlet) dark matter candidate.
