SLAC Large Detector (SLD)

The SLAC Large Detector (SLD) made use of the unique capabilities of the Stanford Linear Collider (SLC) to perform studies of polarized Z particles (or Z0 bosons) produced in collisions between polarized electrons and positrons. This detector stands six stories tall.

The SLD collected data on the production of the Z0 boson using a polarized electron beam. This will lead to the most precise measurement of a crucial parameter in particle physics theory as well as unique measurements on B-mesons. Recent running with SLD confirms a predicted small preference for producing the Z0 boson when the beam is polarized with the spins rotating about the beam axis in a left-handed sense. This distinction between left- and right-handedness at the fundamental particle level is one of the most intriguing phenomena in subatomic physics.

The SLD collaboration consists of about 150 physicists from many Universities and Laboratories who built, maintained, and analyzed data from the SLD detector.

A history of the SLD development is available. The SLD Event Pictures Collection shows computer generated reconstruction of a number of Z particle decays as reconstructed by the SLD detector.
