The UCL Centre for Cosmology, Particle Physics and Phenomenology (CP3) hosts research on high energy particle physics, cosmology, phenomenology and theory of the fundamental interactions. It is strong on both the experimental and theoretical fronts. The aim of the Centre is to bring together researchers in these scientific fields and to encourage collaboration.
