Single Production of Fourth Family $t^{\prime }$ Quarks at LHeC

Abstract

We study the single production of fourth-family $t^{\prime }$ quarks via the process $ep\to t^{\prime }\nu$ at 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 single $t^{\prime }$ quark up to the mass of 800 GeV for the optimized mixing parameters.
