Using the constraints from unitarity and oblique parameters, we show that a heavy Higgs allows large mass splittings in these sectors, opening up new decay channels involving W emission. A Higgs heavier than $ \\sim 800 GeV $ would in fact necessitate either a heavy quark decay channel t'-> b'W/b'-> t' W or a heavy lepton decay channel \\tau' -> \\nu' W as long as the mixing between the third and fourth generations is ","authors_text":"Amol Dighe, Arun Prasath, Diptimoy Ghosh, Rohini M.
