The Higgs boson decay branching fraction is constrained to values less than 6% for proper decay lengths of 10-100 mm and for LLP masses between 40 and 55 GeV. In the case of low-mass (approximate to 15 GeV) scalar particles that subsequently decay to a pair of b quarks, the search is sensitive to branching fractions B(H -> SS) < 20% for proper decay lengths of 10-50 mm. The use of associated production with a Z boson increases the sensitivity to low-mass LLPs of this analysis with respect to gluon fusion searches. In the case of 15 GeV scalar LLPs, the improvement corresponds to a factor of 2 at a proper decay length of 30 mm.]]> Fri 08 Dec 2023 13:19:30 KRAT ]]> Search for Higgs boson pair production in the four b quark final state in proton-proton collisions at √s = 13 TeV https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:001000085 Fri 08 Dec 2023 13:19:29 KRAT ]]>
