Results with published or submitted paper

  • Top Turns Ten!

  • Latest CDF results and Recent talks by CDF speakers
  • All CDF papers
  • Information about the CDF Vertex b-tag algorithm
    • Last updated February 18 2005 with 15% higher b-tag efficiency
  • Information about the CDF jet energy scale.
    • Last updated February 22 2005 with about 50% reduction in total uncertainty from previous Run II estimate. This is the majority of the work needed for the world's best top quark mass measurement released by CDF on March 31 2005.
