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 ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:001002968 Tue 20 Jun 2023 23:18:36 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:001001431 Fri 19 May 2023 14:48:00 KRAT ]]> https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:001001393 Fri 19 May 2023 11:39:06 KRAT ]]> 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 ]]>
