Possible method for finding a heavy Higgs boson

We investigate the detectability in a very-high-energy pp collider of a heavy neutral Higgs boson through the decay modes $H^0$→$Z^0$ $Z^0$→eeee (the so-called ‘‘gold-plated’’ events) and $H^0$→$Z^0$ $Z^0$→eeνν, with a special emphasis on the importance of the backgrounds due to the production of $Z^0$+jets and pure standard QCD jets. A realistic Monte Carlo program is used to simulate the characteristics of signals and backgrounds, and filtering strategies for extracting the signals are proposed.
