The Carleton Theoretical Particle Physics group is one of the largest phenomenology groups in Canada, focusing on the connection between particle theory and experiments. The group is composed of five faculty members, four research associates, four PhD students, and four MSc students. We study models of new physics and how they might be detected by experiments. If unexpected experimental results are found, we aim to disentangle the underlying theory. Most recently, members of the group have worked on Higgs physics and physics beyond the Standard Model as can be studied at the LHC and the future ILC e+e- collider. In addition, we study a broad range of topics in particle physics ranging from hadronic physics to dark matter.
