Teachers and Students This is the dawn of an exciting age of new discovery in the study of elementary particles and their interactions. The current theoretical framework of the fundamental nature of matter, known as the Standard Model, explains much, but leaves many unanswered questions. What is dark matter? What happened to antimatter? Are there extra dimensions of spacetime? Are there new symmetries of nature? Are there new, as yet unobserved, forces? What is responsible for mass? The Large Hadron Collider (LHC), a huge scientific instrument at CERN, will provide the highest-energy particle collisions produced in a laboratory to six experiments that hold the potential to answer these questions. |
