A high-rate trigger stream in combination with a novel low-momentum hadronic tau reconstruction algorithm have enabled a measurement of the $Y(1S,2S,3S)\\to\\tau^+\\tau^-$ process in the challenging environment of a hadron collider, with a $5.8\\sigma$ significance above background and production cross section of $3.5\\pm0.71(\\mathrm{stat})\\pm0.71(\\mathrm{syst})~\\mathrm{nb}$ for $|y|<1.2$ and $p_{\\mathrm{T}}^{\\mathrm{vis}}>15~\\mathrm{GeV}$. No significant excess above the standard model background is observed. Upper limits on the product of the scalar resonance production cross section and branching fraction to $\\tau\\tau$ are set at $95\\%$ confidence level between 40--400 pb.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.167050.v1/t1","@type":"Dataset","description":"The observed $m_{\\text{vis}}(\\mu,\\tau_{\\mathrm{h}})$ distribution in the Y meson selection region is shown with fit results overlaid.
