We reconsider observables for discovering a heavy Higgs boson (with m_h >2m_W) via its di-leptonic decays h -> WW -> l nu l nu. We show that observablesgeneralizing the transverse mass that take into account the fact that both ofthe intermediate W bosons are likely to be on-shell give a significantimprovement over the variables used in existing searches. We also comment onthe application of these observables to other decays which proceed vianarrow-width intermediates.
