Description
This Dark Sector search in the ATLAS collaboration
uses Higgs boson exotic decays as a possible portal
to such new phenomena. Use is made of the Standard Model
(SM) decay to four leptons:
H-->ZZ*-->4l
The current analysis is sensitive to the possible existence
of "Dark Sector" or "Hidden Sector" vector boson ("Zd") or
pseudoscalar boson ("a") that is beyond the SM:
H-->ZZd-->4l (electrons and muons)
H-->Za-->4l ( models suggest that this is mainly to muons)
Analysis results from the full Run 2 dataset (36 inverse fb from 2016)
and (20 inverse fb from 2015) will be presented.
