The 2008 Nobel Prize in Physics was awarded to Kobayashi, Maskawa, and Nambu for their work on symmetry breaking and CP violation. BaBar, together with Belle at KEK, confirmed the prediction of CP violation and they are explicitely mentioned in the Nobel Press Release. See also related articles at: SLAC Today, Nature, Science, Symmetry Magazine.
The BaBar experiment has been built, primarily, to measure CP-violation, a delicate asymmetry between matter and antimatter. This asymmetry is thought to explain why the Universe is made pre-dominantly of matter (and not of antimatter). BaBar has measured this asymmetry for the first time in the decays of neutral Beauty mesons.
The experiment has been running at the PEP-II electron-positron collider (also known as the Beauty Factory), at the Stanford Linear Accelerator Center in California, since May 1999 and is scheduled to take data through to 2008. Current collected luminosity can be found here.

The QMUL group is actively involved in several analyses. Here are some recent highlights:
Previous activity was in the measurement of the radiative penguin decay b->sgamma, Phys.Rev.D72:052004,2005 [aiXiv:hep-ex/0508004], Phys.Rev.Lett. 93 (2004) 021804 [arXiv:hep-ex/0403035], Phys.Rev.Lett. 88 (2002) 101805 [arXiv:hep-ex/0110065v1].
