Search for decays of the Higgs boson into scalar particles decaying into four or six b quarks using pp collisions at (Formula presented) = 13 TeV with the ATLAS detector

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
