  "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) $$_L$$ L doublet model with hypercharge $$Y=-\\frac{1}{2}$$ Y = - 1 2 . Assuming mixing with muons, we study the subsequent decay $$N\\rightarrow W^+ \\mu ^-$$ N → W + μ - and analyze two representative signals, namely $$4j2\\mu $$ 4 j 2 μ and $$2\\ell 2\\mu E\\hspace{-5.83328pt}/$$ 2 ℓ 2 μ E / , 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 $$\\mathcal {L}=4$$ L = 4 ab $$^{-1}$$ - 1 for the unpolarized and polarized beam configurations, $$(P_{\\mu ^+},P_{\\mu ^-})=(0,0)$$ ( P μ + , P μ - ) = ( 0 , 0 ) and $$(P_{\\mu ^+},P_{\\mu ^-})=(-1,1)$$ ( P μ + , P μ - ) = ( - 1 , 1 ) . We consider VLL masses in the range of $$1300{-}2980$$ 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 $$4j2\\mu $$ 4 j 2 μ and $$2\\ell 2\\mu E\\hspace{-5.83328pt}/$$ 2 ℓ 2 μ E / signals, particularly for the idealized fully polarized beam configuration, under the detector, polarization, luminosity and background assumptions adopted in this analysis.",
