Measurement of the tau lifetime at SLD.
We present an updated measurement of the tau lifetime at SLD. 4316-pair events, selected from a 150k Z 0 data sample, are analyzed using three techniques: decay length, impact parameter, and impact parameter diierence methods. The measurement beneets from the small and stable interaction region at the SLC and the precision CCD pixel vertex detector of the SLD. The combined result is: = 288:1 6:...
متن کاملA preliminary , precise measurement of the average B hadron lifetime SLD
A preliminary, precise measurement of the average B hadron lifetime Abstract The average B hadron lifetime was measured using data collected with the SLD detector at the SLC in 1993. From a sample of ∼50,000 Z 0 events, a sample enriched in Z 0 → bb was selected by applying an impact parameter tag. The lifetime was extracted from the decay length distribution of inclusive vertices reconstructed...
متن کاملTHE MEAN RESIDUAL LIFETIME OF PARALLEL SYSTEMS WITH TWO EXCHANGEABLE COMPONENTS UNDER THE GENERALIZED FARLIE-GUMBEL-MORGENSTERN MODEL
The parallel systems are special important types of coherent structures and have many applications in various areas.In this paper we consider a two-exchangeable-component parallel system for the Generalized Farlie-Gumbel-Morgenstern (Generalized FGM) distribution. We study the reliability properties of the residual lifetime of the system under the condition that both components of the system ar...
متن کاملMeasurement of the B + and
The lifetimes of B + and B 0 mesons have been measured using a sample of 400,000 hadronic Z 0 decays collected by the SLD experiment at the SLC between 1993 and 1998. This inclusive topological measurement includes 250,000 hadronic Z 0 decays collected since 1996 with the SLD upgrade vertex detector. A high statistics sample of 30028 19636 charged neutral vertices with good charge purity is obt...
متن کاملComponent and System Tests of the SLD Cerenkov Ring Imaging Detector
The components of the SLD barre1 Cerenkov Ring Imaging Detector (GRID) are now built and are being installed. We report on tests of these, including tests of the fiber optic calibration system, detailed studies of electron drift paths on production drift boxes and detectors, tests of the dynamic gating system and its effect on drift path distortions due to space-charge, and a measurement of the...
