The search uses pp collision data collected with the ATLAS detector at the LHC with an integrated luminosity of 139 fb(-1) at a centre-of-mass energy root s = 13 TeV. The data are found to be consistent with Standard Model expectations. Limits are set on fiducial cross sections and on the branching ratio of the Higgs boson to decay into XX/ZX, improving those from previous publications by a factor between two and four. Limits are also set on mixing parameters relevant in extensions of the Standard Model containing a dark sector where X is interpreted to be a dark boson.]]> Wed 07 Jun 2023 15:15:33 KRAT ]]> Observation of electroweak production of two jets in association with an isolated photon and missing transverse momentum, and search for a Higgs boson decaying into invisible particles at 13 TeV with the ATLAS detector https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:001002733 Sat 17 Jun 2023 08:38:50 KRAT ]]> Search for resonant pair production of Higgs bosons in the b¯bb¯b final state using pp collisions at √s=13 TeV with the ATLAS detector https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:001001431 Fri 19 May 2023 14:48:00 KRAT ]]> Search for single production of a vectorlike T quark decaying into a Higgs boson and top quark with fully hadronic final states using the ATLAS detector https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:001001393 Fri 19 May 2023 11:39:06 KRAT ]]> Constraints on Higgs boson production with large transverse momentum using H→b¯b decays in the ATLAS detector https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:001001392 b (b) over bar process. The 95% confidence-level upper limit on the cross section for Higgs boson production with transverse momentum above 450 GeV is 115 fb, and above 1 TeV it is 9.6 fb. The Standard Model cross section predictions for a Higgs boson with a mass of 125 GeV in the same kinematic regions are 18.4 fb and 0.13 fb, respectively.]]> Fri 19 May 2023 11:39:05 KRAT ]]>
