“…The systematic uncertainties on the tt, W + W − , and Z 0 → τ + τ − acceptances, summarized in Table II, result from uncertainties in the jet energy scale (JES) [13], the modeling of the initial-state radiation (ISR) by pythia [and for the case of tt also final-state radiation (FSR)], the uncertainty on the parton distribution functions [19], the modeling of E sig T , and uncertainties in the lepton trigger and identification efficiencies. The E sig T systematic uncertainty does not apply to the Z 0 → τ + τ − cross section measurement, as we fit for this only in the eμ channel.…”

We present a new method for studying high-p T dilepton events (e ± e ∓ , µ ± µ ∓ , e ± µ ∓ ) and simultaneously extracting the production cross sections of pp → t t, pp → W + W − , and pp → Z 0 → τ + τ − at a center-of-mass energy of √ s = 1.96 TeV. We perform a likelihood fit to the dilepton data in a parameter space defined by the missing transverse energy and the number of jets in the event. Our results, which use 360 pb −1 of data recorded with the CDF II detector at the Fermilab Tevatron Collider, are σ(t t) = 8.5 +2.7 −2.2 pb, σ(W + W − ) = 16.3 +5.2 −4.4 pb, and σ(Z 0 → τ + τ − ) = 291 +50 −46 pb.

“…Each of those corrections has a corresponding fractional uncertainty, σ JES (p T ) which can be parameterized as function of the corrected transverse momentum of the jet p T . They are applied in a sequence of levels (of "L-levels'") in order to correct for each bias independently [59].…”

“…The procedure used to estimate the L5 correction factor is described accurately in [59] and uses a MC sample of inclusive dijet events simulated with PYTHIA [60]. The correction is derived comparing particle jets, which are jets at generator level (before they are passed through the detector simulation), with calorimeter jets, which are reconstructed from the detector simulation.…”

We present the results of a search for new particles that lead to a Z boson plus jets in p p collisions at s p 1:96 TeV using the Collider Detector at Fermilab (CDF II). A data sample with a luminosity of 1:06 fb ÿ1 collected using Z boson decays to ee and is used. We describe a completely data-based method to predict the dominant background from standard model Z jet events. This method can be similarly applied to other analyses requiring background predictions in multijet environments, as shown when validating the method by predicting the background from W jets in t t production. excess above the background prediction is observed, and a limit is set using a fourth generation quark model to quantify the acceptance. Assuming BR b 0 ! bZ 100% and using a leading-order calculation of the b 0 cross section, b 0 quark masses below 268 GeV=c 2 are excluded at 95% confidence level.
