Search for time-dependent Bs 0-Bs 0 oscillations using a vertex charge dipole technique
Physical Review D 67:1 (2003)
Abstract:
We report a search for Bs0-Bs0 oscillations using a sample of 400 000 hadronic Z0 decays collected by the SLD experiment. The analysis takes advantage of the electron beam polarization as well as information from the hemisphere opposite that of the reconstructed B decay to tag the B production flavor. The excellent resolution provided by the pixel CCD vertex detector is exploited to cleanly reconstruct both B and cascade D decay vertices, and tag the B decay flavor from the charge difference between them. We exclude the following values of the B s0-B̄s0 oscillation frequency: Δms<4.9 ps-1 and 7.9<Δm s<10.3 ps-1 at the 95% confidence level. © 2003 The American Physical Society.Improved direct measurement of the parity-violation parameter Ab using a mass tag and momentum-weighted track charge
