Ratio of Branching Fractions Br(B->DsD+)/Br(B->D+3Pi)</i>

Ratio of Branching Fractions Br(B⁰ -> D⁺ D_s)/Br(B⁰ -> D⁺ 3 Pi)

Here we summarize the results for the measurement of the ratio of branching fractions Br(B⁰ -> D⁺ D_s)/Br(B⁰ -> D⁺ 3 Pi).
We measuered it for three D_s decay channels.

D_s -> Phi Pi

D_s -> K^* K

D_s -> Pi Pi Pi

And combined them together. Our final result is

Br(B⁰ -> D⁺ D_s)/Br(B⁰ -> D⁺ 3 Pi) = 2.00 +/- 0.16(NC) +/- 0.12(syst) +/- 0.50(BR).

The result was blessed for spring 2005 CKM conference.

There is a summary of blessed results: DsD.ps.
