CP violation measurements at ALEPH
We use the full ALEPH data set at LEP1 of four million hadronic Z decays to measure CP asymmetries in the B/sub d//sup 0/ decay. From 23 B/sub d//sup 0/ to J/ psi K/sub s//sup 0/ decays the value sin 2 beta =0.84/sub -1.04//sup +0.82/+or-0.16 is measured, while from two measurements of the semilepto...
