Measurement of the CP violation parameter sin2ø 1 in B d 0 meson decays
The violation parameter sin2ø 1 of the standard model CP was measured using B d 0-B̄ d 0 meson pairs produced at the Y(4S) resonance. The accompanying B meson was identified from its charged particle decay products. It was shown that the CP violation manifests itself as an asymmetry A(Δ t).
