This is the WEB page summarizing the blessed result for the measurement of the ratio of branching fractions for Bs mesons relative to B0 mesons. The measurement is done on the 355 pb-1 data set and have been blessed in the B Physics Meeting on Thursday Oct 19, 2005. This is an update for our previous measurement done with 243 pb-1

BR(B_s → D_s3 π (φ π) ) / BR(B⁰ → D⁺3π^-) = 1.15 ± 0.12 ± 0.09 ± 0.29(BR) ± 0.17(PR)
BR(B_s → D_s3 π (K^* K) ) / BR(B⁰ → D⁺3π^-) = 1.14 ± 0.21 ± 0.1 ± 0.31(BR) ± 0.17(PR)
BR(B_s → D_s3 π (3 π)) / BR(B⁰ → D⁺3π^-) = 1.19 ± 0.27 ± 0.09 ± 0.33(BR) ± 0.17(PR)

Reconstructed Bs -> Ds 3π where Ds -> φ π
