A data sample of proton-proton collisions at $\\sqrt{s}$ = 13 TeV corresponding to an integrated luminosity of 138 fb$^{-1}$ recorded with the CMS detector is analyzed. No statistically significant excess is observed over the standard model backgrounds. Upper limits are set at 95% confidence level (CL) on the Higgs boson branching fraction to $\\mu\\mu$bb and to $\\tau\\tau$bb, via a pair of $\\mathrm{a}_1$s. The limits depend on the pseudoscalar mass $m_{\\mathrm{a}_1}$ and are observed to be in the range (0.17-3.3) $\\times$ 10$^{-4}$ and (1.7-7.7) $\\times$ 10$^{-2}$ in the $\\mu\\mu$bb and $\\tau\\tau$bb final states, respectively. In the framework of models with two Higgs doublets and a complex scalar singlet (2HDM+S), the results of the two final states are combined to determine model-independent upper limits on the branching fraction $\\mathcal{B}$(H $\\to$ $\\mathrm{a}_1\\mathrm{a}_1$ $\\to$ $\\ell\\ell$bb) at 95% CL, with $\\ell$ being a muon or a $\\tau$ lepton. For different types of 2HDM+S, upper bounds on the branching fraction $\\mathcal{B}$(H $\\to$ $\\mathrm{a}_1\\mathrm{a}_1$) are extracted from the combination of the two channels. In most of the Type II 2HDM+S parameter space, $\\mathcal{B}($H $\\to$ $\\mathrm{a}_1\\mathrm{a}_1$) values above 0.23 are excluded at 95% CL for $m_{\\mathrm{a}_1}$ values between 15 and 60 GeV.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.145999.v1/t1","@type":"Dataset","description":"Observed and expected upper limits at 95% CL on B($\\text{H} \\rightarrow \\text{a}_{1}\\text{a}_{1} \\rightarrow \\mu\\mu$bb) as functions of $m_{\\text{a}_{1}}$.
