Finding Higgs bosons heavier than 2 m_W in dileptonic W-boson decays    [PDF]

Alan J. Barr, Ben Gripaios, Christopher G. Lester
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 observables generalizing the transverse mass that take into account the fact that both of the intermediate W bosons are likely to be on-shell give a significant improvement over the variables used in existing searches. We also comment on the application of these observables to other decays which proceed via narrow-width intermediates.
