41	Studies of Heavy Baryons in DELPHI and Radiation Monitoring in DØ Berntzon, Lisa January 2004 (has links) <p>Between the years 1992 and 1995 about 3.5 million hadronic Z decays were collected by the DELPHI detector at CERN. This data has been used to measure the production and lifetime of the beauty strange baryon Ξ<sub>b</sub>,</p><p>in the inclusive decay channel Ξ<sub>b</sub> →Ξ<sup>-</sup>ℓ<sup>-</sup> X.</p><p>The Ξ<sup>-</sup> baryon was reconstructed through the decay </p><p>Ξ<sup>-</sup> → Λ π<sup>-</sup>, using</p><p>a constrained fit method for cascade decays. An iterative</p><p>discriminant analysis was used for the Ξ<sub>b</sub> selection.</p><p>A search for the Ξ<sub>b</sub> baryon was also performed using</p><p>an alternative method of reconstructing the Ξ<sup>-</sup> baryon.</p><p>A measurement of the production of the charmed strange </p><p>baryon Ξ<sub>c</sub> in the decay channel Ξ<sub>c </sub>→ Ξ<sup>-</sup>π<sup>+</sup> </p><p>using the same data is also presented.</p><p>The radiation monitoring system of the Silicon Microstrip Tracker </p><p>in the DØ detector is studied and used to estimate </p><p>the radiation dose received by the Silicon detector</p><p>during normal running conditions of the TeVatron accelerator.</p> high energy physics baryons Physics Fysik
