Investigation of Inclusive CP asymmetries in $B^{0}$ decays

The full data set collected with the Aleph detector from 1991 to 1995 at LEP, is analysed to measure the charm forward-backward asymmetry at the Z. Out of a total of 4.1 millions hadronic Z decays, about 40000 high momentum D*+, D+$ and D0's are reconstructed, and the Z -> c cbar forward-bac...

Sumario:The full data set collected with the Aleph detector from 1991 to 1995 at LEP, is analysed to measure the charm forward-backward asymmetry at the Z. Out of a total of 4.1 millions hadronic Z decays, about 40000 high momentum D*+, D+$ and D0's are reconstructed, and the Z -> c cbar forward-backward asymmetry is measured at three energy points: the Z peak and approximately 2 GeV above and below. From the values obtained, the charm forward-backward asymmetry at the Z pole and the effective electroweak mixing angle are extracted.
