Theoretical Particle Physics

What is the nature of the dark matter that makes up 85% of the Universe's matter? How do neutrinos acquire mass? Why is there more matter than antimatter in the Universe? Is there a right-handed neutrino? To address questions like these, our group studies theories that go beyond the Standard Model of particle physics.

Theoretical aspects of particle physics involve

  • Modelling of elementary particles and their interactions
  • Studying models that can predict new phenomena or explain experimental anomalies
  • Working alongside experiments in determining the prospects of new experiments for further probing of our current theories

Theoretical particle physicists often work in cooperation with experimental collaborations, looking for new ways to probe the inner mechanisms of the Universe, from the Big Bang to solar processes and particle physics at accelerators.

The theoretical particle physics group at KTH is particularly interested in the physics of neutrinos, very light neutral particles related to electrons, and those of dark matter. The research is conducted in projects with members of the faculty and students working in smaller groups with international collaborators all over the world.

Our group also has direct interests in the experimental neutrino oscillation community as members of experimental collaborations such as the European Spallation Source Neutrino Super Beam (ESSnuSB) , Hyper-Kamiokande  and the India-based Neutrino Observatory (INO).
