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->lnul{sup '}nu (l, l{sup '}=e, mu) decay channels are analyzed in 1 fb{sup -1} of data collected by the D0 detector at the Fermilab Tevatron Collider. The measured cross section is sigma(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.
