Search for a <em>W′</em> Boson Decaying to a Top and Bottom Quark Pair in 1.8 TeV <em>pp</em> Collisions

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

The contri- butions from standard model t t and dibosons are weighted as in Table I, while the contributions due to W jets and multijets are rescaled to account for the presence

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

For each sample, we reconstruct the top quark mass using the traditional matrix element technique and compare the reconstructed mass to the true input mass M top for several

After basic event selection, the total expected signal event yield in the current data set is 5:1 0:5 ( 3:5 0:4 ) single (double)-tag events for a Higgs boson with a mass of 115

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
