Анализ проводился на полной статистике событий протон-протонных столкновений за 2015–2018 гг. при энергии в их системе центра масс 13 ТэВ. Для событий с электроном и мюоном в конечном состоянии исследование завершено. Рассчитаны наблюдаемая и ожидаемая статистические значимости сигнала от бозона Хиггса без учета систематических погрешностей. Начато также исследование конечных состояний с двумя мюонами и двумя электронами в случае двух и более адронных струй: предложены критерии отбора событий сигнала от H-бозона и выбрана стратегия для вычитания основного фона от процессов Дрелла–Яна. Показано, что экспериментальные кинематические распределения воспроизводятся моделированием методами Монте-Карло.</p></abstract><trans-abstract xml:lang="en"><p>The authors within the Higgs Boson Working Group of the ATLAS experiment at the LHC performed an analysis of events with two leptons and two hadron jets to study Standard Model Higgs boson properties in the H→WW*→ℓνℓν decay channel in the vector boson fusion production mechanism. The analysis was based on full statistics of proton-proton interactions taken during 2015–2018 year exposures at √s=13 TeV. For the final state with one electron and one muon the study is completed. The observed and expected statistical significances of the signal were calculated without taking into account systematic uncertainties. An investigation of final states with two electrons and two muons and at least two hadronic jets has been started. Signal selection criteria are proposed and a strategy to subtract the main background from Drell–Yan processes was chosen. It is shown that experimental kinematical distributions are reproduced by the MC simulations.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>бозон Хиггса</kwd><kwd>адронные струи</kwd><kwd>эксперимент ATLAS</kwd><kwd>LHC</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Higgs boson</kwd><kwd>hadronic jets</kwd><kwd>ATLAS experiment</kwd><kwd>LHC</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">&lt;em&gt;ATLAS Collab.&lt;/em&gt; // Phys.
