For 1 TeV vector-quark masses, we find that signals with greater than 5 sigma significance can be achieved after 100 fb^-1. More generally, jet mass distributions have the potential to provide signals for heavy states that produce highly boosted weak gauge bosons and/or top quarks.7pages, 5 figures; references addedHigh Energy Physics - PhenomenologyHigh Energy Physics - Experimenttext
