Particle physics is about understanding the universe at the very smallest scales. So far, a remarkably consistent picture has emerged. Our experiments imply that everything in the universe consists of a small number of fundamental particles that are held together by a small number of fundamental forces. Our theory - the Standard Model - which describes these interactions, is so successful that we haven't yet made an experimental measurement that disagrees with a single one of its predictions. Yet, we know that the Standard Model is incomplete, and that there is much left for us to understand.
This year sees the start of the Large Hadron Collider (LHC), a new particle accelerator that will allow us to probe the universe at the smallest scales to date. In this talk I will survey our current understanding of particle physics, describe the LHC, and discuss how it might help us solve some of the biggest mysteries about the universe.
Our General Interest Seminars are an opportunity for distinguished speakers to present new research in physics and related areas. The material presented is suitable for undergraduate level upwards and all members of the School are welcome to attend..
