Available in PDF, EPUB and Kindle. Book excerpt: This analysis focuses on a low mass Higgs boson search with 1.7 fb−1 of data. The focus is on Higgs events in which it is produced in association with a W or Z boson. Such events are expected to leave a distinct signature of large missing transverse energy for either a Z → [nu][nu] decay or a leptonic W decay in which the lepton goes undetected, as well as jets with taggable secondary vertices from the H → b{bar B} decay. Utilizing a new track based technique for removing QCD multi-jet processes as well as a neural network discriminant, an expected limit of 8.3 times the Standard Model prediction at the 95% CL for a Higgs boson mass of 115 GeV/c2 is calculated, with an observed limit of 8.0*SM.
