The search for B s0 oscillations at SLD
Abstract
The SLD experiment at the SLAC Linear Collider has updated three searches for the time dependence of B s0 oscillations. One search uses events with a reconstructed D s meson; a second search uses events with a lepton and a topologically identified charmed meson; and the third uses events in which both a secondary and tertiary vertex are distinguished. The combined analyses are sensitive to values of Δ ms, the oscillation frequency, up to 13.0 ps-1. A preliminary maximum likelihood analysis excludes Δm s<7.6 ps-1 and 11.8< Δm s<14.8 ps-1 at 95% CL. Including this data, the combined world data now imply Δm s>15.0 ps-1 at 95% CL, and are not incompatible with a signal near the expected value, Δm s∼15 ps-1.
