摘要
We analyze some signatures of neutral Higgs bosons, produced in high energy proton-(anti)proton collisions, which decay primarily to top quarks. This channel is clouded by a large irreducible tt background. We investigate the t (t) over bar invariant-mass distribution in the lepton + jets decay mode of It and a ti spin-spin correlation in the dilepton decay mode. At the CERN LHC such Higgs bosons can be detected in the tt invariant-mass spectrum, and the spin-spin correlation studied by us is also sensitive to such a Higgs boson if this particle has a mass below 500 GeV. [S0556-2821(98)06523-0].
