A Search for the Standard Model Higgs Boson in pp → ZH → μ+μ− b b at √s = 1.96 TeV
Abstract
The theory and experiment associated with the Standard Model Higgs
boson is reviewed. A search is underway at Fermilab’s Tevatron accelerator
for Higgs production in the pp → ZH → μ+μ−bb channel at 1.96 TeV.
This study employs an artificial neural network trained on simulated data in
order to quantify the expected difference between a small Higgs signal and a
much larger background. The network is optimized with respect to variable
set, training method, and number of training epochs and hidden neurons.
The optimal network achieves greater signal/background discrimination than
a conventional analysis of the data, thereby reducing the total number of
events required for the detection of the Higgs boson.
