Measurement of sin 2 beta from B -> J/psi K-S(0) with the CDF detector Academic Article uri icon

abstract

  • This paper reports an updated measurement of the standard model CP violation parameter sin 2 using the CDF Detector at Fermilab. The entire run I data sample of 110 pb -1 of proton-antiproton collisions at s = 1.8 TeV is used to identify a signal sample of 400 BJ/K s0 events, where J/ + - + - . The flavor of the neutral B meson is identified at the time of production by combining information 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 determine sin 2=0.79 -0.44+0.41 (stat+syst). This value of sin 2 is consistent with the standard model prediction, based upon existing measurements, of a large positive CP-violating asymmetry in this decay mode. 2000 The American Physical Society.
