An observation of electroweak $W^{\\pm}Z$ production in association with two jets in proton-proton collisions is presented. \nThe data collected by the ATLAS detector at the Large Hadron Collider in 2015 and 2016 at a centre-of-energy of $\\sqrt{s}$ = 13TeV are used, corresponding to an integrated luminosity of 36.1 $fb^{-1}$. \nEvents containing three identified leptons, either electrons or muons, and two jets are selected. \nThe electroweak production of $W^{\\pm}Z$ bosons in association with two jets is measured with an observed significance of 5.3 standard deviations. \nA fiducial cross section for electroweak production including interference effects is measured to be $\\sigma_{WZjj-EW}$ = 0.57^{+0.14}_{-0.13} (stat.) ^{+0.07}_{-0.06} (syst.) fb. \nDifferential cross section of $W^{\\pm}Zjj$ production for several kinematic observables are also measured.\n\nFiducial phase space definition for the measurement:\n- $p_{\\mathrm{T}}$ of electrons and muons from Z0 decays &gt; 15 GeV\n- $p_{\\mathrm{T}}$ of electrons and muons from the $W^{\\pm}$ decays &gt; 20 GeV\n- $|\\eta|$ of muons and electrons &lt; 2.5\n- Leptons from the Z0 boson are separated by $\\Delta R(\\ell,\\ell) &gt; 0.2$ from each other\n- Leptons from the Z0 and W bosons are separated by $\\Delta R(\\ell,\\ell) &gt; 0.3$ from each other\n- |dilepton mass - Z0 mass| &lt; 10 GeV\n- $m_{\\mathrm{T}}$ of $W^{\\pm}$ &gt; 30 GeV.\n \n- at least 2 jets with opposite $|\\eta|$.
