  "abstract": "The single production of first-generation $\\mathrm{SU}(2)_L$ doublet vector-like leptons (VLLs) at the Compact Linear Collider (CLIC) with $\\sqrt{s}=3~\\mathrm{TeV}$ is studied. The neutral and charged VLL states are investigated through $e^+e^-\\rightarrowν_e\\bar N+\\barν_eN$ and $e^+e^-\\rightarrow e^\\pm E^\\mp$, respectively. The neutral VLL is searched for in the $N\\rightarrow W^\\mp e^\\pm$ channel with $W^\\pm\\rightarrow jj$, leading to the $e^\\pm+2j+\\slashed{E}_T$ final state. The charged VLL is explored through $E^\\pm\\rightarrow e^\\pm h$ ($h\\rightarrow b\\bar b$) and $E^\\pm\\rightarrow e^\\pm Z$ ($Z\\rightarrow q\\bar q$), yielding the $e^+e^-+2b$ and $e^+e^-+2j$ signatures. Signal and background simulations include initial-state radiation, beamstrahlung, and detector effects. Cut-based analyses are performed for integrated luminosities of $1$, $3$, and $5~\\mathrm{ab}^{-1}$ to obtain the exclusion and discovery sensitivities in the VLL mass--mixing parameter space. The neutral-VLL channel gives the best sensitivity. At $1~\\mathrm{ab}^{-1}$, the $2σ$ exclusion reaches $\\varepsilon\\simeq0.013$ at $M_N=1.3~\\mathrm{TeV}$ and $\\varepsilon\\simeq0.065$ at $M_N=2.9~\\mathrm{TeV}$, while the $5σ$ discovery reach corresponds to $\\varepsilon\\simeq0.02$--$0.10$. At $5~\\mathrm{ab}^{-1}$, the charged-VLL channels probe masses up to about $2.9~\\mathrm{TeV}$ and $2.8~\\mathrm{TeV}$ in the $e^\\pm h$ and $e^\\pm Z$ modes, respectively. These results demonstrate that a 3 TeV CLIC can provide sensitive probes of first-generation doublet VLLs over a wide mass range, including scenarios with small VLL--electron mixing.",
