ATLAS searches conducted for a BSM light boson using as portal events where a Higgs
boson with mass 125 GeV decays to four leptons will be reported. This decay is presumed
to occur via an intermediate state which contains one or two on-shell, promptly decaying
bosons: H → ZX/XX → 4l, where X is a new dark vector boson Ζd (or a pseudo-scalar α),
with mass between 1 and 60 GeV. These exotic Higgs decays searches using pp collisions
data collected with the ATLAS detector at the LHC will be described. The results are found
to be consistent with SM background predictions and limits are set with interpretations in
specific benchmark theory models.
