AB  - A search for the electroweak production of a Higgs boson in association with a same-sign W boson pair and two forward jets (W^±W^±Hjj) is presented. The full Run 2 proton-proton collision dataset recorded at a center-of-mass energy of √s=13 TeV by the ATLAS detector at the Large Hadron Collider is used, corresponding to an integrated luminosity of 140 fb^−1. The search targets events where both W bosons decay leptonically, yielding a final state with two same-sign charged leptons, missing transverse momentum, and a Higgs boson candidate. The high-momentum Higgs-boson candidate decaying into a bb̅ pair is reconstructed as a single large-radius jet. This process provides direct sensitivity to the quartic WWHH interaction. Possible deviations from the Standard Model prediction are parameterized through the coupling modifier κ_WW, where κ_WW=1 corresponds to the Standard Model. No significant excess over the Standard Model prediction is observed. Upper limits at the 95% confidence level are set on the W^±W^±Hjj production cross-section as a function of κ_WW. Observed (expected) values of κ_WW outside the interval −2.1 < κ_WW < 4.1 (−1.9 < κ_WW < 3.9) are excluded.
