Abstract
A search for exotic decays of the Higgs boson 𝐻 into new scalar or pseudoscalar particles that subsequently decay into 𝑏-quarks is presented. The search considers 𝑍𝐻 production with several decay scenarios for the Higgs boson; first to a pair of identical scalars, 𝐻 →2𝑎 →4𝑏, second to a pair of scalars with different masses (𝑚𝑎1 <𝑚𝑎2), either directly, 𝐻 →𝑎1𝑎2 →4𝑏, or via a longer decay chain, 𝐻 →𝑎1𝑎2 →3𝑎1 →6𝑏. The analysis uses proton-proton collision data at √𝑠 =13 TeV collected with the ATLAS detector at the Large Hadron Collider, corresponding to an integrated luminosity of 140 fb−1. No significant excess above the Standard Model prediction is observed. The search sets upper limits at 95% confidence level on the ratio of the Higgs boson production cross section to the SM prediction times the branching ratio of Higgs bosons decaying into 4𝑏 or 6𝑏, between 4% and 25% for 𝜎(𝑍𝐻)/𝜎SM(𝑍𝐻)×ℬ(𝐻→2𝑎→4𝑏), between 24% and 38% for 𝜎(𝑍𝐻)/𝜎SM(𝑍𝐻)×ℬ(𝐻→𝑎1𝑎2→4𝑏), and between 10% and 20% for 𝜎(𝑍𝐻)/𝜎SM(𝑍𝐻)×ℬ(𝐻→𝑎1𝑎2→3𝑎1→6𝑏), depending on the masses of the scalar particles.
