A search for the neutral Higgs boson in the mass range above 11 GeV (above the H0-> b bbar threshold), using the process Z0 -> H0e+e-, Z 0-> H0 mu+mu- and H0 -> nu nubar, is performed on data collected by the ALEPH detector corresponding to about 25000 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.

Abstract
A search for the neutral Higgs boson in the mass range above 11 GeV (above the H0-> b bbar threshold), using the process Z0 -> H0e+e-, Z 0-> H0 mu+mu- and H0 -> nu nubar, is performed on data collected by the ALEPH detector corresponding to about 25000 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.File in questo prodotto:
