Dear Colleagues, The joint DZero and CDF Higgs Sensitivity Study is available online at: http://www-d0.fnal.gov/Run2Physics/public/higgs/HSS_D0_CDF.pdf To quote from the executive summary: "The Tevatron is currently the only accelerator capable of producing a low mass Higgs boson. Understanding the sensitivity of the Tevatron experiments to either observe or rule out a low mass standard model Higgs boson is important. (...) These studies assumed the Run IIB detector upgrades, including the silicon vertex detectors, which were under construction at that time. While this manuscript was in progress, the Fermilab Director canceled the upgrades of the silicon vertex detectors. This decision impacts the results of this study primarily through the capabilities of the experiments to tag bottom quarks from the decay of the Higgs boson. The b-quark tagging using the current silicon detectors will likely degrade due to radiation damage when the integrated luminosity exceeds ~4/fb. We are in the process of determining the sensitivity using the current silicon detectors for the duration of Run II." Norman Graf
