| dc.description.abstract | This paper presents a dedicated search for exotic decays of the Higgs boson to a pair of new spin-zero particles, $H \rightarrow aa$ , where the particle a decays to b-quarks and has a mass in the range of 20–60 GeV. The search is performed in events where the Higgs boson is produced in association with a $W$ boson, giving rise to a signature of a lepton (electron or muon), missing transverse momentum, and multiple jets from b-quark decays. The analysis is based on the full dataset of pp collisions at $\sqrt{s} = 13\,\mathrm{{TeV}}$ recorded in 2015 by the ATLAS detector at the CERN Large Hadron Collider, corresponding to an integrated luminosity of 3.2 $\text{ fb }^{-1}$ . No significant excess of events above the Standard Model prediction is observed, and a $95\,\%$ confidence-level upper limit is derived for the product of the production cross section for $pp \rightarrow WH$ times the branching ratio for the decay $H \rightarrow aa \rightarrow 4b$ . The upper limit ranges from 6.2 pb for an a-boson mass $m_a = 20\,\mathrm{{GeV}}$ to 1.5 pb for $m_a = 60\,\mathrm{{GeV}}$ . | |
