Particle Physics is the study, both experimentally and theoretically, of the fundamental constituents of matter and their interactions. It includes the study of how different subatomic particles interact with one another,  their properties like mass and charge, and their production and decay mechanisms.

Experimental Particle Physicists use cutting-edge modern detectors to probe these particles to gain understanding about their properties and to see if there could be any new particles that are waiting to be discovered! Examples of these include the ATLAS detector at the Large Hadron Collider in Switzerland, SNO+ at SNOLAB in Canada, n2EDM, NOvA, and DEAP.

Theoretical Particle Physicists use computer simulations and advanced mathematical models to develop the models, framework, and mathematical tools to understand data coming from current experiments and to make predictions for future experiments.

At Sussex the Experimental Particle Physics and the Theoretical Particle Physics groups aim to answer some of the fundamental questions posed by modern physics, such as: What is the origin of mass? Why is there more matter than antimatter in the Universe? Is there physics beyond the Standard Model?

The University of Sussex offers a specialised taught postgraduate MSc degree and fully funded PhD positions in experimental particle physics and theoretical particle physics.
