| Abstract: | Assuming the Higgs scalar boson H0 of the standard model has mass mH>2MZ, we show that the popular four-lepton decay signature H0→ZZ→ℓ1+ℓ1−ℓ2+ℓ2− at the SSC can be significantly enhanced relative to the continuum ZZ background by requiring high transverse momentum for at least one Z. The calculated signal is sensitive to the top quark mass. |
