Abstract
We provide the most precise measurement of the WW production cross section in pp-bar collisions to date at a center of mass energy of 1.96 TeV, and set limits on the associated trilinear gauge couplings. The WW→ℓνℓ′ν (ℓ, ℓ′=e, μ) decay channels are analyzed in 1 fb(−1) of data collected by the D0 detector at the Fermilab Tevatron Collider. The measured cross section is σ(pp-bar→WW)=11.5±2.1(stat+syst)±0.7(lumi) pb. One- and two-dimensional 95% C.L. limits on trilinear gauge couplings are provided.
