Physics Colloquium

"Strange Beauty and the Matter/Antimatter Puzzle"

Presented by Christoph Paus, MIT

Tuesday, November 29, 2005, 3:30 pm — Small Seminar Room, Bldg. 510

The vast majority of the visible universe is composed of matter and very little antimatter is observed, although from the big bang one would naively expect to find equal amounts. One crucial component for trying to explain this apparent asymmetry is the phenomenon of CP violation.

In the last five years experiments at the experiments at the B factories and the hadron collider Tevatron have made remarkable progress in measuring this phenomenon in decays of B mesons. We will focus on the unique contributions from the Tevatron where Bs (say: B sub s) mesons are used to probe the Standard Model. Bs mesons are composed of one strange and one anti-beauty quark.
