The sld Genetic Defect

The cellular basis of the genetically determined hemopoietic defect in anemic mice of genotype Sl-Sld.

First Results from Sld with Polarized Electron the Sld Collaboration

The SLAC Linear Collider (SLC) has been modified to collide a longitudinally polarized electron beam with the unpolarized positron beam. We review the beginning of polarized beam running at the SLC, and report on the measurement of the left-right cross section asymmetry (ALR) made with a sample of 10,224 Z decays collected over the course of the 1992 run. The average beam polarization for this ...

We present a direct measurements of the Z 0-lepton coupling asymmetries, A e , A , and A. It is based on a data sample selected from 170k Z 0 decays collected by the SLD detector. The Z's are produced by collisions of polarized e , with unpolarized e + bunches at SLC. The couplings are extracted from the measurement of the left-right forward-backward asymmetry for each lepton species. The preli...

We have developed a new technique for inclusive reconstruction of the energy of B hadrons. The excellent efficiency and resolution of this technique allow us to make the most precise determination of the b-quark fragmentation function, using e + e − → Z 0 decays recorded in the SLD experiment at SLAC. We compared our measurement with the predictions of a number of fragmentation models. We exclu...

We present preliminary results of a new measurement of the inclusive b quark fragmentation function in Z 0 decays using a novel kinematic B hadron energy reconstruction technique. The measurement is performed using 150,000 hadronic Z 0 events recorded in the SLD experiment at SLAC between 1996 and 1997. The small and stable SLC beam spot and the CCD-based vertex detector are used to reconstruct...
