Search for Higgs boson decays into a pair of light bosons in the bbμμ final state in pp collision at s√=13 TeV with the ATLAS detector Aaboud, M. Aguilar Saavedra, Juan Antonio Atlas Collaboration A search for decays of the Higgs boson into a pair of new spin-zero particles, H→aa, where the a-bosons decay into a b-quark pair and muon pair, is presented. The search uses 36.1 fb−1 of proton-proton collision data at s√=13 TeV recorded by the ATLAS experiment at the LHC in 2015 and 2016. No significant deviation from the Standard Model prediction is observed. Upper limits at 95% confidence level are placed on the branching ratio (σH/σSM)×B(H→aa→bbμμ), ranging from 2×10−4 to 10−3 in the a-boson mass range of 20-60 GeV. Model-independent limits are set on the visible production cross-section times the branching ratio to the bbμμ final state for new physics, σvis(X)×B(X→bbμμ), ranging from 0.1 fb to 0.73 fb for mμμ between 18 and 62 GeV. 2020-03-09T11:47:51Z 2020-03-09T11:47:51Z 2018-12-21 info:eu-repo/semantics/article Clark, PJ, Farrington, S, Faucci Giannelli, M, Gao, Y, Hasib, A, Leonidopoulos, C, Martin, VJ, Mijovic, L, Wynne, B & Collaboration, A 2019, 'Search for Higgs boson decays into a pair of light bosons in the $bb\mu\mu$ final state in $pp$ collision at $\sqrt{s} = $13 TeV with the ATLAS detector', Physics Letters B, vol.
