This WEB page summarizes the blessed results for the evidence of the decay
of the *Bc* meson to *J/psi pi* and measurement of the *Bc* mass.
to be shown to the winter conferences 2005 The results have been blessed in the *B*
Physics Meeting on Thursday November 18, 2004.

There is a complete version of the results: hep-ex/0505076

Below are the eps versions of all figures meant for downloads.

** Main results**

- Figure 1 - mass_plot_bu.eps .................Mass distribution for B+ candidates, using the same cuts (no upper ct)
- Figure 2 - fit_scan.eps ...........................Result of the fit scan in the search region.
- Figure 3 - Mass_plot_bc_full_10.eps ...Mass distribution for J/Psi pi candidates in the full search window
- Figure 4 - Final_Mass_Fit_Blessed.eps Mass distribution for J/Psi pi candidates in the fit region
