Abstract
We study the electroweak single production of fourth-family t' quarks via the process ep $\rightarrow$ t'$\nu$ at the Large Hadron electron Collider (LHeC). We calculate the background and signal cross-sections for the mass range 300–800 GeV. It is shown that the LHeC can discover a single t' quark up to the mass of 750 GeV for the optimized mixing parameters.
