The observed dimuon invariant mass distribution is consistent with the Standard Model background-only hypothesis in the 120-150 GeV search range. For a Higgs boson with a mass of 125.5 GeV, the observed (expected) upper limit at the 95 % confidence level is 7.0 (7.2) times the Standard Model expectation. This corresponds to an upper limit on the branching ratio BR($H \rightarrow \mu^+\mu^-$) of $1.5\times10^{-3}$.engSearch for the Standard Model Higgs boson decay to $\mu^{+}\mu^{-}$ with the ATLAS detectorjournal article2019-02-04
