 Investigation of Inclusive CP Asymmetries in B$^{0}$ Decays
 ALEPH Collaboration(s)
 (2001)
 A search for CP violating effects in the mixing of neutral B mesons is performed using a sample of 4.1 million hadronic Z decays collected with the ALEPH detector from 1991 to 1995. By studying time-dependent asymmetries in flavour-tagged samples of semileptonic and fully inclusive b-hadron decays, two measurements of the semileptonic asymmetry a_cp are extracted. No evidence for CP violation is observed, and the combined value a_cp = -0.013 +- 0.026 is obtained.
