  New vector-like quarks can mix sizably with first generation Standard Model
quarks without conflicting with current experimental constraints. Searches for
such new quarks have been performed in pair production and electroweak single
production channels with subsequent decays into electroweak gauge bosons. To
fully explore the underlying structure of the theory the channels with heavy
quark decays into Higgs bosons are crucial and in this article we consider for
the first time the LHC reach for such channels. The two main production
mechanisms involve single production of new quarks through the fusion of a
vector boson and the Higgs and single production in association with a Higgs
boson. We show that both channels have promising reach at the LHC and that they
complement the current direct searches involving decays into electroweak gauge
bosons.
