Observation of electroweak W${}^{+}$W${}^{-}$ pair production in association with two jets in proton-proton collisions at $\sqrt{s}$ = 13 TeV

CMS Collaboration

An observation is reported of the electroweak production of a W${}^{+}$W${}^{-}$ pair in association with two jets, with both W bosons decaying leptonically. The data sample corresponds to…
