Search for Higgs Bosons Decaying to <em>bb</em> and Produced in Association with <em><strong>W</strong></em> Bosons in <em>pp</em> Collisions at s√=1.96  TeV

The observed number of events and the dijet mass distributions are consistent with the standard model background expectations, and we set 95% confidence level upper limits on

We present the first measurement of the production cross section of a W boson with a single charm quark (c) in pp collisions at s√=1.96  TeV, using soft muon tagging of c jets.. In

Events from t t production followed by leptonic W decay typically have two b jets from t decay, significant missing transverse energy, and one or two high-energy leptons with two

The Z jets and Z jets background contributions are estimated from data by extrapolating from a sample of events that contain three identified leptons and a jet j l containing a

IX. CROSS SECTION LIMIT CALCULATION To extract the signal from the data a Bayesian-based statistical procedure is applied. The region between 60 and 120 GeV of the m jj distribution

Sources of systematic uncertainty in the background yield of tagged b jets include the uncertainty in the b -jet tagging efficiency in the data (a relative 6% uncertainty on all
