A search for the dimuon decay of the Standard Model Higgs boson with the ATLAS detectorHigh Energy Physics - Experiment44 pages in total, author list starting page 28, 2 figures, 3 tables, Published by Phys. Lett. B. All figures including auxiliary figures are available at https://atlas.web.cern.ch/Atlas/GROUPS/PHYSICS/PAPERS/HIGG-2019-14A search for the dimuon decay of the Standard Model (SM) Higgs boson is performed using data corresponding to an integrated luminosity of 139 fb$^{-1}$ collected with the ATLAS detector in Run2 $pp$ collisions at $\sqrt{s}=13$ TeV at the Large Hadron Collider. The observed (expected) significance over the background-only hypothesis for a Higgs boson with a mass of 125.09 GeV is $2.0\,\sigma$ ($1.7\,\sigma$). The observed upper limit on the cross section times branching ratio for $pp \to H \to \mu\mu$ is 2.2 times the SM prediction at 95% confidence level, while the expected limit on a $H \to \mu\mu$ signal assuming the absence (presence) of a SM signal is $1.1$ ($2.0$). The best-fit value of the signal strength parameter, defined as the ratio of the observed signal yield to the one expected in the SM, is $\mu = 1.2 \pm 0.6$.We thank CERN for the very successful operation of the LHC, as well as the support staff from our institutions without whom ATLAS could not be operated efficiently.
