title = "Direct measurement of Ab in Z0 decays using charged kaon Tagging",
abstract = "We present a direct measurement of the parity-violating asymmetry Ab in the Z0 to b{\=b} coupling using a new technique to distinguish the b and {\=b} quarks using charged kaons from B decays. The Z0 bosons are produced in e+ē collisions at the SLC with longitudinally polarized electrons. b{\=b} events are selected using a secondary vertex mass tag and Ab is determined from the left-right forward-backward asymmetry. From the 1994–1995 data sample, selected from 100 000 hadronic Z0 decays, we obtain Ab = 0.855 ± 0.088stat ± 0.102syst.",
