This webpage collects the links to the CDF public note and to the
relevant supporting plots for the measurement of the branching
fractions of the B^{0}_{s} →π^{+}π^{-}
and B^{0} →K^{+}K^{-} decays.
These preliminary results were approved on May 19^{th},2011
by the CDF collaboration.

A complete description of the analysis is available here: CDF Public note 10498.

We report the first evidence of the B
