Bs Oscillations at CDF

Abstract


The Bs meson transforms into its own anti-particle and back with a frequency that is known to be higher than 16.6 ps^-1. Observing this oscillation and measuuring the oscillation frequency will constrain certain elemements of the CKM matrix and, as such, could be sensitive to new physics. Observing Bs oscillation is one of the major goals of CDF at the Tevatron, which is currently the only accelerator where Bs mesons are produced. There are considerable experimental challenges, for example due to the high frequency of the oscillation, which demands very good lifetime resolution. I will discus the motivation for measuring Bs oscillation, the experimental techniques involved in the analysis and the latest results from CDF.
