[PAST EVENT] Physics Colloquium
Teppei Katori, Queen Mary University of London, Title of Talk: Search of Space-Time Defect: The race to Defeat Einstein
Abstract: Einstein's theory of relativity is based on the perfect space-time symmetry law, called Lorentz symmetry. However, modern theories, such as string theory, allow possible violation of this space-time structure. Because of this, there is a world-wide effort to look for the violation of Lorentz symmetry, or Lorentz violation, using state-of-the-art techniques with lasers, pendulums, particle accelerators, etc. On the other hand, modern particle physics is focusing on study of neutrinos, so called ghost particles. These mysterious neutrinos are perhaps the key to discover Lorentz violation! In this talk I would like to introduce Lorentz violation and some of the recent tests, and conclude the search for Lorentz violation using neutrinos.
