"Higgs Boson Searches at the CDF Experiment: Highlights of UVa Contributions to a Successful Search with the Full Data Set"
 
 Slideshow (PDF)
ABSTRACT:
I present the results from the CDF experiment on the direct searches for a Standard Model Higgs boson produced in p-pbar collisions at a center of mass energy of 1.96 TeV, using the data corresponding to integrated luminosity of up to 10fb-1. The searches are performed in the Higgs boson mass range from 100 to 200 GeV/c2. The dominant decay channels, H → bb and H → W W , are combined with all the secondary channels and significant analysis improvements have been recentlyimplemented to maximize the search sensitivity. UVa contributions to these analyses, their recent improvements, and to the leadership of the effort are highlighted. The results from the CDF experiment are combined with the D0 experiment, both using their full data sets, and a significant excess of data events compared to background prediction is reported. The highest local significance is 3.0 standard deviations while global significance for such an excess anywhere in the full mass range investigated is approximately 2.5 standard deviations. Both experiments at the Large Hadron Collider have recently reported excesses of greater than 5standard deviations in their searches for the Higgs boson. The complementarity and relevance of the Tevatron results are discussed in the context of this recent discovery from the LHC.
