The main goal of the experiment is to perform a complete study of CP violation (CP is the symmetry linking particules and antiparticules) in the system of B mesons.
More generally the experiment studies the physics of heavy flavors: mesons and baryons with a b or a c quark and tau leptons.
The ARGUS experiment at Hambourg and the CLEO experiment at Cornell in the eighties and nineties were the first "B factories" built to study the physics of B mesons. BABAR and the BELLE experiment at KEK in Japan are "B factories" from the second generation. They are able to study CP violation.
The energy content of the Universe/Antimatter and CP violation.
Data taking started in may 1999.
Contribution from Dapnia
Dapnia played a major role in the construction and running of the DIRC detector (1995-1998). The DIRC is the main detector for particle identification in BABAR.
In particular, Dapnia is responsible for:

Scope of the experiment
The BABAR experiment has been one of the major experiment in High Energy Physics during the past years. Dapnia and SPP have been heavily involved with a maximum of 14 physicists at the same time.
