SuperB Experiment

SuperB is a high luminosity e+e- collider that will be dedicated to elucidating new physics through precision studies of rare or suppressed decays. The collider will be built near Rome under the supervision of Istituto Nazionale di Fisica Nucleare (the Italian National Institute for Nuclear Physics, INFN).[1] The title SuperB refers to the fact that the collider is expected to produce very large quantities of B mesons.[1]

Physics

The designers hope that SuperB will help to provide evidence about the flavour sector of the Standard Model[2] SuperB is intended to give further information about any new physics found by the Large Hadron Collider. It may also be able to check for violations of CP violation, which may contribute to an understanding of why the universe is full of matter and not antimatter. Accepted physical theory indicates that at the Big Bang equal quantities of matter and antimatter were created. However, when matter and antimatter meet they annihilate one another, so we should expect the universe to be empty. Physicists believe that CP violation may account for the discrepancy, and the designers hope that SuperB may be able to throw light on the question.[3] They expect that SuperB will be able to make much more precise checks for CP violation than has been possible in the past.[4]

SuperB should make it possible to observe matter and antimatter coexisting much as they did in the first moments of the universe, by means of the Uncertainty Principle. Unfortunately this situation is very unstable, and lasts for only a very brief time, but it is hoped to be able to take billions of quick glimpses, and thus build up a picture of what is happening.[5]
