AI中文摘要：
本文报道了对希格斯玻色子与同号$W$玻色子对及两个前向喷注（$W^{\pm}W^{\pm}Hjj$）电弱联合产生的搜索。研究使用了大型强子对撞机上ATLAS探测器在质心能量$\sqrt{s}=13$ TeV下记录的全部Run 2质子-质子碰撞数据，对应积分亮度为140 fb$^{-1}$。搜索针对两个$W$玻色子均轻子衰变的事件，产生包含两个同号带电轻子、缺失横动量及一个希格斯玻色子候选者的终态。高动量希格斯玻色子候选者衰变为$b\bar{b}$对，被重建为单个大半径喷注。该过程直接敏感于四线性$WWHH$相互作用。与标准模型预言的可能偏差通过耦合修正因子$\kappa_{WW}$参数化，其中$\kappa_{WW}=1$对应标准模型。未观察到相对于标准模型预言的显著超出。在95%置信水平上，对$W^{\pm}W^{\pm}Hjj$产生截面作为$\kappa_{WW}$的函数设置了上限。观测（期望）排除的$\kappa_{WW}$值区间为$-2.1 < \kappa_{WW} < 4.1$（$-1.9 < \kappa_{WW} < 3.9$）之外。
英文摘要：
A search for the electroweak production of a Higgs boson in association with a same-sign $W$ boson pair and two forward jets ($W^{\pm}W^{\pm}Hjj$) is presented. The full Run 2 proton-proton collision dataset recorded at a center-of-mass energy of $\sqrt{s}=13$ 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 $b\bar{b}$ 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 $W^{\pm}W^{\pm}Hjj$ 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.
