Caption: BaBar particle detector. Physicists and engineers working on the open BaBar particle detector at the Stanford Linear Accelerator Center (SLAC), California, USA. It is hoped that BaBar will help explain why there is more matter than antimatter in the universe. BaBar will detect the B mesons and their antimatter equivalents, anti-B mesons, that result from the collisions of electrons and positrons circulated in opposite directions around the two rings of the PEP-II collider. The collisions will occur at the centre of this cylindrical device. To explain the greater amount of matter in the universe, B mesons should decay at a different rate from anti-B mesons.
