Summary
We present selected new results on strong interaction physics from the SLD experiment at the SLAC Linear Collider (SLC), symmetry tests of b anti-bg vertex, the rate of secondary b anti-b production via gluon splitting, the B hadron energy spectrum and rapidity correlations between identified charged hadrons. The parity violation in Z° --> b anti-bg decays is consistent with electroweak theory plus QCD. New tests of T- and CP-conservation at the bbg vertex are performed. A new measurement of the rate of gluon splitting into b anti-b pairs yields g{sub b anti-b} = 0.00307 ± 0.00071 (stat.) ± 0.00066 (syst.) (Preliminary). The B hadron energy spectrum is measured using a new inclusive technique, allowing tests of predictions for its shape and a measurement of (x{sub B} = 0.714 ± 0.005 (stat.) ± 0.007 (stat.) (Preliminary)). A study of correlations in rapidity between pairs of identified pi{sup ±}, K{sup ±} and p/anti-p confirms that strangeness and baryon number are conserved locally, and shows local charge conservation between meson-baryon and strange-nonstrange pairs. Flavor-dependent long-range correlations are observed for all combinations of these hadron species. The first study of correlations using signed rapidities is done and find the first direct observation of baryon number ordering along the q/anti-q axis.
