Search for exotic Higgs boson decays into two pseudoscalar bosons in the bbmumu final state using pp collisions at √s = 13.6 TeV with the ATLAS detector.

Results from a search for an exotic Higgs boson decay into two pseudoscalar particles "a", where one "a" decays into two b-quarks and the other into two muons. The search is performed in the mass range of 14 < ma < 62 GeV. This presentation uses 168 fb⁻¹ of proton-proton collision data collected at a center-of-mass energy of √s = 13.6 TeV in the ATLAS experiment at the LHC during Run 3 from 2022 to 2024. The analysis strategy and the current status of the search will be discussed.
