The Oregon effort included building and operating the SLD luminosity monitor and collaboration on the SLD vertex detector. The Oregon OPAL group collaborated on the luminosity monitor upgrade to a silicon-tungsten calorimeter. Oregon contributed to the construction, commissioning, and writing reconstruction software for this calorimeter. The experiment used a new sign-selected beam to achieve unprecedented accuracy for measurements of the weak mixing angle in neutrino interactions. The experiment ran during 1996-97 and exceeded data collection goals.
Analysis is in progress and first results have been presented.
