Physics Results from SLD Using the CRID
Abstract
We review recent Z0 physics results from SLD that use the Cherenkov Ring Imaging Detector for charged particle identification. The performance of the detector and likelihood method are described briefly. Several hadronization measurements are presented, including identified hadron production in events of different primary flavors, leading hadron production, and new correlation studies sensitive to details of both leading and nonleading hadron production. Identified K+- have been used in conjunction with precision vertexing to study charmless and doubly charmed B-hadron decays. This combination has also been used to tag b, b-bar, c and c-bar jets, yielding precise measurements of B0-B0bar mixing and of the asymmetric couplings Ab and Ac. Identified K+- and Lambda0 have been used to tag s and s-bar jets, yielding a measurement of As. The clean identified particle samples provided efficiently by the CRID allow the purities of these tags to be measured from the data, an essential ingredient for precision physics.
