First measurement of the left-right cross section asymmetry in Z boson production at E[sub cm] = 91. 5 GeV (open access)

First measurement of the left-right cross section asymmetry in Z boson production at E[sub cm] = 91. 5 GeV

The left-right cross section asymmetry for Z boson production in e[sup +] e[sup [minus]] annihilation (A[sub LR]) is being measured at E[sub cm] 91.5 GeV with the SLD detector at the SLAC Linear Collider (SLC) using a longitudinally polarized electron beam. The electron polarization is continually monitored with a Compton scattering polarimeter, and is typically 22%. At the current time, we have accumulated a sample of 4779 Z events. We find that A[sub LR] = 0.02 [double bond] 0.07 [doteq] 0.001 where the first error is statistical and the second is systematic. Using this very preliminary measurement, we determine the weak mixing angle defined at the Z boson pole to be sin[sup 2][sub W][sup olept] = 0.247 [plus minus] 0.009.

Quality Assurance Program Description---DWPF. Revision 1 (open access)

Quality Assurance Program Description---DWPF. Revision 1

This document describes the Westinghouse Savannah River Company`s (WSRC) Quality Assurance Program for Defense Waste Processing at the Savannah River Site (SRS). It identifies and describes the planned activities that constitute the required Quality Assurance Program. The work to which the Quality Assurance Program applies includes both the qualification and production of high-level waste forms. The end result of the program is to provide confidence that these high-level waste forms may be safely and acceptably used to dispose of the radioactive waste that results from activities at SRS in support of national defense.

Interpretation of rapidly rotating pulsars (open access)

Interpretation of rapidly rotating pulsars

The minimum possible rotational period of pulsars, which are interpreted as rotating neutron stars, is determined by applying a representative collection of realistic nuclear equations of state. It is found that none of the selected equations of state allows for neutron star rotation at periods below 0.8--0.9 ms. Thus, this work strongly supports the suggestion that if pulsars with shorter rotational periods were found, these are likely to be strange-quark-matter stars. The conclusion that the confined hadronic phase of nucleons and nuclei is only metastable would then be almost inescapable, and the plausible ground-state in that event is the deconfined phase of (3-flavor) strange-quark-matter.
