  "abstract": "Vector-like leptons (VLLs) are well-motivated candidates for physics beyond the standard model. We investigate the sensitivity of the $6$ TeV muon collider to the neutral doublet VLL (denoted by $N$) via its pair production in an SU(2)$_L$ doublet model with hypercharge $Y=-\\frac{1}{2}$. Assuming mixing with muons, we study the subsequent decay $N\\rightarrow W^+ μ^-$ and analyze two representative signals, namely $4j2μ$ and $2\\ell2μE\\mkern-10.5 mu/$, arising from the hadronic and leptonic decays of the $W$ boson, respectively. The signal and background events are simulated within a Monte Carlo framework, and a cut-based analysis is performed at the $6$ TeV muon collider with an integrated luminosity $\\mathcal{L}=4$ ab$^{-1}$ for the unpolarized and polarized beam configurations, $(P_{μ^+},P_{μ^-})=(0,0)$ and $(P_{μ^+},P_{μ^-})=(-1,1)$. We consider VLL masses in the range of $1300-2980$ GeV and evaluate the corresponding search sensitivity. Our results show that the $6$ TeV muon collider could provide strong sensitivity to neutral doublet VLLs through the $4j2μ$ and $2\\ell2μE\\mkern-10.5 mu/$ signals, particularly for the idealized fully polarized beam configuration, under the detector, polarization, luminosity and background assumptions adopted in this analysis.",
