Abstract

We present a new method for studying high- $p_{T}$ dilepton events ( $e^{\pm} e^{\mp}$ , $μ^{\pm} μ^{\mp}$ , $e^{\pm} μ^{\mp}$ ) and simultaneously extracting the production cross sections of $p \bar{p} \to t \bar{t}$ , $p \bar{p} \to W^{+} W^{-}$ , and $p \bar{p} \to Z^{0} \to τ^{+} τ^{-}$ at a center-of-mass energy of $\sqrt{s} = 1.96 TeV$ . 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 $360 p b^{- 1}$ of data recorded with the CDF II detector at the Fermilab Tevatron Collider, are $σ (t \bar{t}) = {8.5}_{- 2.2}^{+ 2.7} pb$ , $σ (W^{+} W^{-}) = {16.3}_{- 4.4}^{+ 5.2} pb$ , and $σ (Z^{0} \to τ^{+} τ^{-}) = 291_{- 46}^{+ 50} pb$ .

In the CDF coordinate system, $θ$ and $ϕ$ are the polar and azimuthal angles, respectively, with respect to the proton beam direction ( $z$ axis). The pseudorapidity $η$ is defined as $- \ln \tan (θ / 2)$ . The transverse momentum of a particle is $p_{T} = p \sin θ$ . The analogous quantity using calorimeter energies, defined as $E_{T} = E \sin θ$ , is called transverse energy.
The missing transverse energy, ${\vec{E̸}}_{T}$ , is defined as $- \sum_{}^{} E_{T}^{i} {\hat{n}}_{i}$ , where ${\hat{n}}_{i}$ is the unit vector in the transverse plane pointing from the interaction point to the energy deposition in calorimeter cell $i$ . The ${\vec{E̸}}_{T}$ measurement is corrected for muons in the event with $p_{T} > 20 GeV / c$ , and for jet corrections. The magnitude of ${\vec{E̸}}_{T}$ is denoted as ${E̸}_{T}$ .

The calorimeter isolation $I_{cal}$ is defined as the extra energy deposited in the calorimeter cone of radius $Δ R = \sqrt{Δ ϕ^{2} + Δ η^{2}} =$ 0.4 around the lepton. The $I_{cal}$ is required to be less than 10% of the lepton $E_{T}$ .
The track isolation $I_{trk}$ is defined as the sum of the $p_{T}$ of all the tracks in a cone of radius $Δ R = \sqrt{Δ ϕ^{2} + Δ η^{2}} = 0.4$ around the lepton candidate track, but excluding it. The $I_{trk}$ is required to be less than 10% of the lepton track $p_{T}$ .

We compared the acceptances obtained using MRST 72 and 75 PDF sets [29], corresponding to $α_{s} = 0.1175$ and 0.1125, respectively. Also we include the effect of the eigenvector variations around the fit minima, using CTEQ6M PDF sets [30], and used the maximum variation observed in the acceptance as our systematic uncertainty.
