Searching for single production of a vector-like $Y$ quark decaying into $bW$ at the FCC-eh

Liangliang Shang, Weifan Zhu, Bingfang Yang +1

We investigate the exclusion and discovery potential for single production of a vector-like $Y$ quark with electric charge $Q=-4/3$, followed by the decay $Y\to bW$, at the FCC-eh.…
