The analysis is performed using a data sample of proton-proton collisions collected with the CMS detector at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 138 fb−1. To reduce the background from standard model processes, the search requires the Higgs boson to be produced in association with a leptonically decaying W or Z boson. The analysis probes the production of new light bosons in a 15 < ma < 60 GeV mass range. Assuming the standard model predictions for the Higgs boson production cross sections for pp → WH and ZH, model independent upper limits at 95% confidence level are derived for the branching fraction BH→aa→bb¯bb¯. The combined WH and ZH observed upper limit on the branching fraction ranges from 1.10 for ma = 20 GeV to 0.36 for ma = 60 GeV, complementing other measurements in the μμττ, ττττ and bbℓℓ (ℓ = μ, τ) channels. © The Author(s) 2024.Springer Science and Business Media Deutschland GmbH2024Articlehttps://rdlopen.rawdatalibrary.net/r/ebyu/11751https://doi.org/10.1007/jhep06(2024)0971029-8479enJournal of High Energy Physicsinfo:eu-repo/semantics/openAccessinfo:eu-repo/semantics/articlehttps://ebyu-rdlopen.rawdatalibrary.net/tr/items/ebyu/11751
