We study the pair production of the vector-like lepton singlet decaying into
at the International Linear Collider (ILC) with the center-of-mass
in a simplified model. Considering the polarized degrees of electron and photon beams
,
, we implement a detailed detector simulation of the signal and backgrounds. For comparison, we investigate the search at leptonic channel and hadronic channel of the W boson, respectively. We find that the ILC can exclude (discover) the region
[180 GeV, 240 GeV] with an integrated luminosity of
([0.305, 1.102]
) in the hadronic channel, and can exclude (discover) the region
[180 GeV, 240 GeV] with an integrated luminosity of [1.83, 19.4]
([11.7, 117.8]
) in the leptonic channel. If these two results are combined, we find that the ILC can exclude (discover) the region
[180 GeV, 240 GeV] with lower integrated luminosity.
