The observation of the electroweak production of a W+W− pair in association with two jets, with both W bosons decaying leptonically, is reported. The data sample corresponds to an integrated luminosity of 138fb−1 of proton-proton collisions at s = 13 TeV, collected by the CMS detector at the CERN LHC. A signal is observed (expected) with a significance of 5.6 (5.2) standard deviations with respect to the background-only hypothesis..
