Measurement of the <em>W⁺W⁻</em> Production Cross Section and Search for Anomalous <em>WWγ</em> and <em>WWZ</em> Couplings in <em>pp</em> Collisions at √s=1.96  TeV

Using the dilepton decay channel W+W−→ℓ+νℓ−ν¯, where the charged leptons can be either electrons or muons, we find 17 candidate events compared to an expected background

The likelihood ratio distribution for signal (dashed line) from PYTHIA MC samples and background (solid line) from data sidebands in the U-U channel. Distributions of the

We estimate the background contribution from W events with only light-flavor jets by applying the mistag rate, measured in the inclusive jet data set and parametrized in jet E T , ,

6 The p T distributions of the B and J= mesons in the data are slightly softer than those of the simulation; this difference is not relevant for the result of the study because the B

We begin the signal reconstruction by requiring the candidate muon, pion, and kaon tracks to satisfy COT fiducial and quality selection criteria, which include re- quirements on

Geometric and kinematic acceptance The acceptance of t t events in this analysis is measured in PYTHIA and then corrected, using measurements from the data, for effects that are
