Search for the neutral Higgs boson from Z0 decay

Description
A search for the neutral Higgs boson, using the processes Z0→H0e+e-, Z0→H0μ+μ-, Z0→H0τ+τ-, Z0→H0νanti ν and Z0→H0qanti q, is performed on data collected by the ALEPH detector corresponding to about 11 550 events of Z0→hadrons. Combining all these processes, the mass range excluded is 32 MeV-15 GeV at 95% CL and 40 MeV-12 GeV at 99% CL. The result from this experiment is unambiguous in the context of the standard model.
