Measurement of Time-Dependent CP Asymmetries and the CP -Odd Fraction in the Decay B0→D*+D*−
B. Aubert, R. Barate, D. Boutigny, F. Couderc et autres
We present an updated measurement of time-dependent $CP$ asymmetries and the $CP$-odd fraction in the decay ${B}^{0}\ensuremath{\rightarrow}{D}^{*+}{D}^{*\ensuremath{-}}$ using $232\ifmmode\times\else\texttimes\fi{}{10}^{6}B\overline{B}$ pairs collected by the BABAR detector at the SLAC PEP-II $B$ factory. We determine the $CP$-odd fraction to be $0.125\ifmmode\pm\else\textpm\fi{}0.044(\mathrm{stat})\ifmmode\pm\else\textpm\fi{}0.007(\mathrm{syst})$. The time-dependent $CP$ …
