The BaBar detector was built at SLAC to study the millions of B mesons produced by the PEP-II storage ring.
The BaBar Collaboration consists of physicists and engineers from institutions in several countries.

  October 2008 The 2008 Nobel Prize in Physics was awarded to Kobayashi, Maskawa, and Nambu for their work on symmetry breaking and CP violation. Understanding the origins of CP violation is one of the primary goals of the experimental programs of both the BaBar and Belle experiments, which were mentioned by name in the Nobel press release. The BaBar Collaboration has prepared a statement explaining the meaning and importance of this work. [Poster Link]
