  We study resonances decaying to one top quark and one additional quark (b or
c) at the low- luminosity and high-luminosity 14 TeV LHC and at a future 33 TeV
hadron collider in the context of Snowmass 2013. A heavy W boson that
preferentially couples to quarks can be found through its decay to tb. A
Kaluza-Klein gluon might have a significant branching ratio to tc. The final
state in these searches has a lepton and neutrino from a W boson decay plus two
jets, at least one of which is b-tagged. We give expected limits as a function
of W boson and KKg masses for different collider energy and integrated
luminosity options.
