We explore the generic structure of neutrino spectrum generated in the presence of bilinear and trilinear R-parity violating couplings. We also study the effect of nondegeneracy of the sneutrinos. We also invoke abelian flavour symmetry to explain the order of magnitudes of the R-parity violating parameters and investigate whether this scenario is compatible with the data.

We present our measurements of the Z0 boson to b and c quark production fractions, Rb and Rc, as well as the results of our search for Flavor Changing Neutral Currents in Z0 decays through the measurement of Rbs=Z->bs/Z->hadrons using the 96-98 SLD data sample of 400K hadronic Z0 decays. We extract Rb, Rc, and Rbs simultaneously using a multi-tag method. These measurements rely on the unique features of the SLD experiment, especially the high resolution CCD vertex detector, the micron size beam spot, and the Cherenkov Ring Imaging Detector used for particle identification.

The progress in astrophysics and cosmology in recent years provides many new questions and new motivations for particle physics. A working Group of the American Linear Collider Physics Group has been formed and charged with evaluating the connections of linear collider physics to astrophysics and cosmology. We will describe the goals of this subgroup, the central topics to be explored, and some of the outstanding questions we seek to answer. A preliminary organizational plan and timeline have been developed. We will present this plan and timeline, solicit advice and reactions, and answer questions for potential contributors.
