Laboratory

The Theoretical Physics Laboratory of Particles (LPTP) at EPFL, led by Riccardo Rattazzi, focuses on fundamental physics questions such as the unification of forces, electroweak symmetry breaking, mass hierarchies, dark matter, and the early universe. Research includes supersymmetry, grand unification, and effective field theory methods for cosmological evolution.
