Measurement of the WW Production Cross Section with Dilepton Final States in pp Collisions at s~(1/2) = 1.96 TeV and Limits on Anomalous Trilinear Gauge Couplings

摘要

We provide the most precise measurement of the WW production cross section in pp collisions to date at a center of mass energy of 1.96 TeV, and set limits on the associated trilinear gauge couplings. The WW → eve'v (e, e' = 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→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.
