We provide the most precise measurement of the WW production cross section in p{bar p} collisions to date at a center of mass energy of 1.96 TeV, and set limits on the associated trilinear gauge couplings. The WW {yields} {ell}{nu}{ell}{prime}{nu} ({ell},{ell}{prime} = 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}(p{bar p} {yields} 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.
