The aim of Particle Physics is to understand matter and the fundamental forces in the universe and ultimately form a Theory of Everything. The Standard Model of Particle Physics beautifully brings together three of the four forces of nature (strong, electromagnetic and weak) in a framework encompassing 6 quarks and 6 leptons, and the gauge particles which mediate their interactions (photons, W bosons, Z bosons and gluons). Ultimately, we hope to incorporate the fourth force in nature, gravity, into this Standard Model.

Big Bang models of the formation of our universe typically predict that our world should be equal parts matter and antimatter. However, all indications are that our universe is dominated by matter, and something happened to all the antimatter.

The BaBar experiment was designed to study the matter-antimatter asymmetry of the universe... and along the way we are also producing one of the world's largest samples of beautiful and charmed mesons, so we can also do some pretty nifty precision studies on these heavy short-lived particles.


Science
The physics of the beautiful quark and CP violation (matter-antimatter asymmetry) is the central focus of the BaBar experiment.
People
The BaBar collaboration consists of physicists and engineers from 75 institutions in 10 countries. At UBC, we have 3 Faculty members, 2 Research Associates, plus about half a dozen graduate and undergraduate students at any given time. We have sufficient funding to recruit about 2 new graduate students per year- plus a couple of summer or co-op students.
Facilities
The UBC Particle Physics group has its own computing facilities, access to electronics and machine shops and infrastructure at TRIUMF, and pleasant lab and office space.
The Experiment
The BaBar detector is located at SLAC at the collision point of the PEP-II storage ring. The BaBar drift chamber was assembled here in Canada (at TRIUMF) and installed in the detector at SLAC in 1998.
Key Publications
Babar and SLAC press releases, published papers and other documentation is available online.
Join UBC BaBar
The UBC BaBar group can take on a couple of promising graduate and undergraduate students each year.
