Abstract
A search for the neutral Higgs boson, using the processes , is performed on data collected by the ALEPH detector corresponding to about 11550 events of Z0-> hadrons. Combining all these processes Z0->H0 e+ e-, Z0->H0 mu+ mu-, Z0->H0 tau+ tau-,Z0->H0 q qbar 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.File in questo prodotto:
