Physics results from SLD using the CRID

We review recent Z0 physics results from SLD that use CRID 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, b̄, c and c̄ jets, yielding precise measurements of B0-B̄0 mixing and of the asymmetric couplings Ab and Ac. Identified K± and Λ0/Λ̄0 have been used to tag s and s̄ 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.
