Abstract

A search for the neutral Higgs boson in the mass range above 11 GeV (above the threshold), using the process Z0→H0e+e−, Z0→H0μ+μ− and , is performed on data collected by the ALEPH detector corresponding to about 25 000 events of Z0→ hadrons. Combining all these processes, the mass range excluded is 11 GeV at 95% CL. Together with a previously published result from ALEPH, the mass range excluded is 32 MeV to 24 GeV at 95% CL. This result also extends the excluded mass region for neutral Higgs bosons from supersymmetry.
