Recent Electroweak Results from SLC/SLD

Description

Key electroweak measurements performed by the SLD collaboration at the SLC are described and recent results given. The left-right cross-section asymmetry, ALR, has been updated to include the 1996 data. It remains the single most precise measurement of sin2 θWeff, and it is compared to the LEP results. The polarized differential cross section for b-quarks is measured and is used to perform a unique direct measurement of the parity violation parameter for b quarks, Ab. The excellent capability to perform secondary vertexing at SLC with CCD-based vertex detectors is described, including first physics results with the new detector VXD3. The vertexing is used to full advantage to make a highly pure B tag to measure the fraction of hadronic Z0 decays going to b quarks, Rb. The vertexing, in combination with electron-beam polarization, is used to measure Bd0 mixing. The prospects for making a Bs0 mixing measurement are excellent given good SLC performance in the upcoming SLC run(s)
