Contribution

It provides new experimental measurements of branching fractions for various rare B decays using a large dataset from the BABAR experiment.

Findings

Measured branching fractions for several rare B decays.

Observed decay modes consistent with Standard Model predictions.

Enhanced understanding of penguin transition processes.

Abstract

We present the results of searches for rare B meson decays. The measurements use all or part of a data sample of about 88 million $\Upsilon(4S)\to B{\bar B}$ decays collected between 1999 and 2002 with the \babar detector at the PEP-II asymmetric energy B Factory at the Stanford Linear Accelerator Center. We study a variety of decays dominated by electromagnetic, electroweak and gluonic penguin transitions, and report measurements of branching fractions and other quantities of interest.
