Contribution

First precise measurements of multiple color-suppressed B decay branching fractions using extensive data from the BaBar experiment.

Findings

Branching fractions measured for eight decay modes.

Results compared with theoretical predictions.

Data set includes approximately 454 million B meson pairs.

Abstract

We report results on the branching fraction ($\mathcal{BF}$) measurement of the color-suppressed decays $\bar{B}^0\to D^0 \pi^0$, $D^{*0}\pi^0$, $D^0\eta$, $D^{*0}\eta$, $D^0\omega$, $D^{*0}\omega$, $D^0\eta^{\prime}$, and $D^{*0}\eta^{\prime}$. The result is based on a sample of $(454\pm 5)\times 10^{6} B\bar{B}$ pairs collected at the $\Upsilon(4S)$ resonance from 1999 to 2007, with the $\babar$ detector at the PEP-II storage rings at the Stanford Linear Accelerator Center. The measurements are compared to theoretical predictions by factorization, SCET and pQCD.
