Abstract (data abstract)
CERN-LHC. Measurements of the electroweak production of a $W$ boson in association with two jets at high dijet invariant mass are performed using $\sqrt{s} = 7$ and 8 TeV proton--proton collision data produced by the Large Hadron Collider, corresponding respectively to 4.7 and 20.2 fb${}^{-1}$ of integrated luminosity collected by the ATLAS detector. The measurements are sensitive to the production of a $W$ boson via a triple-gauge-boson vertex and include both the fiducial and differential cross sections of the electroweak process. Preselection: - Lepton $p_\text{T} > 25$ GeV - Lepton $|\eta| < 2.5$ - $E_\text{T}^\text{miss} > 25$ GeV - $m_\text{T} > 40$ GeV - $p_\text{T}^{j_1} > 80$ GeV - $p_\text{T}^{j_2} > 60$ GeV - Jet $|y| < 4.4$ - $M_{jj} > 500$ GeV - $\Delta y(j_1, j_2) > 2$ - $\Delta R(j,\ell) > 0.3$ Inclusive regions: - $M_{jj} > 0.5$ TeV, 1 TeV, 1.5 TeV, or 2 TeV Forward-lepton/central-jet region: - $N^\text{cen}_\text{lepton} = 0$, $N^\text{cen}_\text{jets} \geq 1$ Forward-lepton control region: - $N^\text{cen}_\text{lepton} = 0$, $N^\text{cen}_\text{jets} = 0$ Central-jet validation region: - $N^\text{cen}_\text{lepton} = 1$, $N^\text{cen}_\text{jets} \geq 1$ Signal region: - $N^\text{cen}_\text{lepton} = 1$, $N^\text{cen}_\text{jets} = 0$ High-mass signal region: - $M_{jj} > 1$ TeV, $N^\text{cen}_\text{lepton} = 1$, $N^\text{cen}_\text{jets} = 0$
