Particle physics

Particle physics is the study of nature's constituents and interactions at the most fundamental level. Perimeter researchers develop theoretical ideas and compare them with data from cosmological observations, Earth-based accelerators, small-scale experiments, and underground laboratories. This process is used to constrain the theoretical possibilities for physics beyond the Standard Model. Particle physics has strong overlaps with Perimeter research in string theory, quantum gravity, and cosmology.
