Abstract

The Large Hadron Collider, a gigantic particle accelerator at the CERN laboratory in Europe, has commenced operation. It will discover how particles gain mass, explore the identity of cosmological dark matter, and search for the new laws of physics needed for a satisfactory theory of the structure of matter. the Centre will provide the enhanced capability and institutional coordination and development needed for Australia to make a major contribution to this most prestigious international project. It will transform Australia's standing in fundamental physics, provide unsurpassed training, generate many linkages in science and technology, and lead an important public outreach program.
