“…The SLD experiment at SLAC used four layers of CCDs in its vertex detector. The first generation CCD-based detector VXD2 [5] consisted of 480 square centimetre-sized CCDs with a total of 120 million pixels, and was replaced in 1995 by VXD3 [6] with 96 large active area (80 mm×16 mm) CCDs and a total of about 300 million 20 µm×20 µm pixels. In VXD3 the sensors were thinned to approximately 150 µm and attached to 400 µm thick beryllium substrates, resulting in a material budget of only 0.4% X 0 per layer in the active region.…”

“…For the measurement of the strange quark asymmetry parameter A s , the first step was to select ss events and tag the s ands jets. We used the SLD Vertex Detector [8] to measure each track's impact parameter d in the plane perpendicular to the beam direction. We then removed cc and bb events by requiring no more than one well-measured track with d larger than 2.5 times its uncertainty.…”

We report results on two physics topics from the SLD experiment at the SLAC Linear Collider, using our full sample of 550,000 events of the type e + e − → Z 0 → qq. The electron beam was polarized, enabling the quark and antiquark hemispheres to be tagged in each event. One physics topic is the first study of rapidities signed such that positive rapidity is along the quark rather than antiquark direction. Distributions of ordered differences in signed rapidity between pairs of particles are analyzed, providing the first direct observation of baryon number ordering along the qq axis. The other topic is the first direct measurement of A s , the parity-violating coupling of the Z 0 to strange quarks, by measuring the left-right forward-backward production asymmetry in polar angle of the tagged s quark. We obtain A s = 0.895 ± 0.066(stat.) ± 0.062(syst.), which is consistent with the Standard Model and is currently the most precise measurement of this quantity.
