Search for Higgs boson decays into a pair of light bosons in the <i>bbμμ</i> final state in pp collision at √s = 13 TeV with the ATLAS detector

A search for decays of the Higgs boson into a pair of new spin-zero particles, <i>H → aa</i>, where the a-bosons decay into a b-quark pair and a muon pair, is presented. The search uses 36.1 fb<sup>−1</sup> of proton–proton collision data at √s = 13 TeV recorded by the ATLAS...

description A search for decays of the Higgs boson into a pair of new spin-zero particles, <i>H → aa</i>, where the a-bosons decay into a b-quark pair and a muon pair, is presented. The search uses 36.1 fb<sup>−1</sup> of proton–proton collision data at √s = 13 TeV recorded by the ATLAS experiment at the LHC in 2015 and 2016. No significant deviation from the Standard Model prediction is observed. Upper limits at 95% confidence level are placed on the branching ratio (σ<sub>H</sub> /σ<sub>SM</sub>)×B(<i>H → aa → bbμμ</i>), ranging from 1.2×10<sup>−4</sup> to 8.4×10<sup>−4</sup> in the a-boson mass range of 20–60 GeV. Model-independent limits are set on the visible production cross-section times the branching ratio to the <i>bbμμ</i> final state for new physics, σ<sub>vis</sub>(X) × B(<i>X → bbμμ</i>), ranging from 0.1 fb to 0.73 fb for m<sub>μμ</sub> between 18 and 62 GeV.
