Wayne State University Dissertations
This dissertation presents a search for the standard model (SM) Higgs boson in the associated production process ZH → l+l- bb using 4.1fb-1 of Tevatron collision data collected with the CDF II detector.
To increase the sensitivity to a ZH signal over previous CDF searches, we implement new electron and expanded b-jet identification algorithms.
We utilize neural network classifiers enhanced with matrix element probabilities, a b-jet identifying neural network, and multivariate jet energy corrections to maximize the separation of signal from SM backgrounds.
We employ three neural network classifiers separately optimized for each of our three …
