Search for standard model Higgs boson production in association with a W boson using a matrix element technique at CDF in pp-bar collisions at s=1.96 TeV

Popis výsledku v původním jazyce

This paper presents a search for standard model Higgs boson production in association with a W boson using events recorded by the CDF experiment in a data set corresponding to an integrated luminosity of 5.6 fb(-1). The search is performed using a matrixelement technique in which the signal and background hypotheses are used to create a powerful discriminator. The discriminant output distributions for signal and background are fit to the observed events using a binned likelihood approach to search forthe Higgs boson signal. We find no evidence for a Higgs boson, and 95% confidence level (C.L.) upper limits are set on sigma(p (p) over bar -> WH) X B(H -> b (b) over bar). The observed limits range from 3.5 to 37.6 relative to the standard model expectation for Higgs boson masses between m(H) = 100 GeV/c(2) and m(H) 150 GeV/c(2). The 95% C.L. expected limit is estimated from the median of an ensemble of simulated experiments and varies between 2.9 and 32.7 relative to the production rat
