Study of Bs oscillations in Bs->Ds(3)Pi

Study of Bs oscillations in Bs->Ds(3)Pi

This web page summarizes the blessed results for the analysis of Bs oscillations in fully reconstructed Bs->Ds(3)Pi samples. Those have been blessed in the B Physics Meeting on Thursday Oct 13, 2005.

There is a complete version of the results: CDF note 7941.

Δms > 0.0 ps^-1 @95 C.L.

expected sensitivity = 9.8 ps^-1

This analysis is an updated version of the Winter 2004 Bs oscillation analysis. The main upgrades include:

Integration of additional fully hadronic modes into an unbinned fit
Use of the Neural Net Jet Charge OST
