Abstract
This paper reports an updated measurement of the standard model CP violatio n parameter sin 2 beta using the CBF Detector at Fermilab. The entire run I data sample of 110 pb(-1) of proton-antiproton collisions at root s =1.8 T eV is used to identify a signal sample of similar to 400 B-->J/psi K-S(o) e vents, where J/psi --> mu(+)mu(-) and K-S(o) - pi(+) pi(-). The flavor of t he neutral B meson is identified at the time of production by combining inf ormation from three tagging algorithms: a same-side tag, a jet-charge tag, and a soft-lepton tag. A maximum likelihood fitting method is used to deter mine sin 2 beta=0.79(-0.44)(+0.41)(stat + syst). This value of sin 2 beta i s consistent with the standard model prediction, based upon existing measur ements, of a large positive CP-violating asymmetry in this decay mode.
