Measurement of Time-Dependent CP Asymmetries and the CP-odd Fraction in the Decay B^0 --> D^{*+}D^{*-}

TL;DR

This paper reports measurements of time-dependent CP asymmetries and the CP-odd fraction in B^0 --> D^{*+}D^{*-} decays using data from the BaBar experiment, providing insights into CP violation in B meson systems.

Contribution

It provides the first measurement of time-dependent CP asymmetries and the CP-odd fraction in this specific B meson decay mode.

Findings

Measured CP asymmetries in B^0 --> D^{*+}D^{*-} decays.

Updated the CP-odd fraction with new data.

Results are preliminary and contribute to understanding CP violation.

Abstract

We present a measurement of time-dependent CP asymmetries and an updated determination of the CP-odd fraction in the decay B^0 --> D^{*+}D^{*-}. The measurements are derived from a data sample of 88 times 10^{6} B bar{B} pairs collected by the BaBar detector at the PEP-II energy asymmetric B Factory at SLAC. All results are preliminary.
