Title: Measurement of BR(B0 -> Ds*+D*-) and Determination of the Ds+ ->

phi pi+

Branching Fraction with a Partial-Reconstruction Method
Authors: The BABAR Collaboration, B. Aubert, et al
Comments: 14 pages, 2 postscript figures, submitted to LP2003

We present model-independent measurements of the branching fractions

${\cal

B}(B^0\to D_s^{*+} D^{*-})$ and ${\cal B}(D_s^+ \to \phi \pi^+)$ based on

19.3

$\textup{fb}^{-1}$ of data collected by the $BABAR$ detector at the PEP-II
$e^+e^-$ $B$ Factory. Neutral $B$-meson decays to the $D_s^{*+}D^{*-}$

final

state are selected with a partial reconstruction of the $D_s^{*+}$; that

is,

only the $D^{*-}$ and the soft photon from the decay $D_s^{*+} \to \Ds

\gamma$

are reconstructed. The branching fraction ${\cal B}(B^0\to D_s^{*+}

D^{*-})$ is

extracted from these event yields, while ${\cal B}(D_s^+ \to \phi \pi^+)$

is

determined by combining this result with a previous measurement of the

product

${\cal B}(B^0\to D_s^{*+} D^{*-}) \times {\cal B}(D_s^+ \to \phi \pi^+)$

with

partial reconstruction of the $D^{*-}$. We obtain the following

preliminary

results:
${\cal B}(B^0\to D_s^{*+} D^{*-}) = (1.50 \pm 0.16 \pm 0.12)%,$
${\cal B}(D_s^+ \to \phi \pi^+) = (4.7 \pm 0.6 \pm 0.8)%$ where the first

error

is statistical, and the second systematic. "



This is why The Smart Model should be used, because at least you can
understand in a simple way what is going on at the sub-atomic level.

The abstract you've posted above is a result of the arxiv not being able to
correctly display TeX source. Run it through a TeX compiler and you'll be
able to read it properly.
