By removing the muon information from the signalsused for reconstruction and identification of the $\\tau_{had}$ candidate in the boosted pair, the efficiency is raised to the level expected for an isolated $\\tau_{had}$. The new procedure is validated by selecting a sample of highly boosted $Z\\rightarrow\\tau_{\\mu}\\tau_{had}$ candidates from the data sample of $140$ ${fb}^{-1}$ of proton--proton collisions at $13$ TeV recorded with the ATLAS detector. Good agreement is found between data and simulation predictions in both the $Z\\rightarrow\\tau_{\\mu}\\tau_{had}$ signal region and in a background validation region. The results presented in this paper demonstrate the effectiveness of the $\\tau_{had}$ reconstruction with muon removal in enhancing the signal sensitivity of the boosted $\\tau_{\\mu}\\tau_{had}$ channel at the ATLAS detector.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.157879.v1/t1","@type":"Dataset","description":"The distribution of the TauID jet RNN score for $\\tau_\\mathrm{had}^{\\mu\\mkern-10mu\\backslash}$ in the SR. `$Z(\\rightarrow\\tau\\tau)$+jets' represents the contributions from the signal...","name":"TauID jet RNN score SR"},{"@id":"https://doi.org/10.17182/hepdata.157879.v1/t2","@type":"Dataset","description":"The distribution of the TauID jet RNN score for $\\tau_\\mathrm{had}^{\\mu\\mkern-10mu\\backslash}$ in the VR. `$Z(\\rightarrow\\tau\\tau)$+jets' represents the contributions from the signal...","name":"TauID jet RNN score VR"},{"@id":"https://doi.org/10.17182/hepdata.157879.v1/t3","@type":"Dataset","description":"The distribution of the $p_\\mathrm{T}{}_{\\mu\\mathrm{-had}}^\\mathrm{col}$ in the SR. `$Z(\\rightarrow\\tau\\tau)+\\text{jets}$' represents the contributions from the signal process. `Diboson' indicates the contributions...","name":"ditau colinear pT SR"},{"@id":"https://doi.org/10.17182/hepdata.157879.v1/t4","@type":"Dataset","description":"The distribution of the $p_\\mathrm{T}{}_{\\mu\\mathrm{-had}}^\\mathrm{col}$ in the VR. `$Z(\\rightarrow\\tau\\tau)+\\text{jets}$' represents the contributions from the signal process. `Diboson' indicates the contributions...","name":"ditau colinear pT VR"},{"@id":"https://doi.org/10.17182/hepdata.157879.v1/t5","@type":"Dataset","description":"The distributions of $m_{\\mu\\mathrm{-had}}^\\mathrm{col}$ corresponding to the SR selection criteria defined in the text. `$Z(\\rightarrow\\tau\\tau)+\\text{jets}$' represents the contributions from the...","name":"ditau colinear mass SR comparison"},{"@id":"https://doi.org/10.17182/hepdata.157879.v1/t6","@type":"Dataset","description":"The distributions of $m_{\\mu\\mathrm{-had}}^\\mathrm{col}$ corresponding to the SR_\\text{std} selection criteria defined in the text. `$Z(\\rightarrow\\tau\\tau)+\\text{jets}$' represents the contributions from the...","name":"ditau colinear mass SR_std comparison"},{"@id":"https://doi.org/10.17182/hepdata.157879.v1/t7","@type":"Dataset","description":"The distributions of $m_{\\mu\\mathrm{-had}}^\\mathrm{col}$ corresponding to the SR_\\text{tight} selection criteria defined in the text. `$Z(\\rightarrow\\tau\\tau)+\\text{jets}$' represents the contributions from the...","name":"ditau colinear mass SR_tight comparison"},{"@id":"https://doi.org/10.17182/hepdata.157879.v1/t8","@type":"Dataset","description":"The distributions of $m_{\\mu\\mathrm{-had}}^\\mathrm{col}$ corresponding to the SR_\\text{tight}^\\text{std} selection criteria defined in the text. `$Z(\\rightarrow\\tau\\tau)+\\text{jets}$' represents the contributions from the...","name":"ditau colinear mass SR_tight_std comparison"},{"@id":"https://doi.org/10.17182/hepdata.157879.v1/t9","@type":"Dataset","description":"The distribution of $\\Delta\\phi^\\mathrm{signed}_{\\mu-MET}$ with all other event selection criteria applied in the SR;
