A search for neutral Higgs particles in Z0 decays
1992
Abstract The search in DELPHI data for neutral Higgs bosons is described. No candidate for the Standard Model Higgs is seen in Z 0 decays to H 0 ν ν , H 0 μ + μ − or H 0 τ + τ − after selections that proved efficient for finding simulated H 0 . One remaining candidate for Z 0 → H 0 e + e − is consistent with background. Together with our earlier studies, these results restrict the H 0 mass to be above 38 GeV/ c 2 at the 95% confidence level. No signal is found for decays of Minimal Supersymmetric Standard Model neutral Higgs bosons to τ + τ − . Limits are obtained for their decays to produce four jets.
