Abstract

The reaction e+e- → HZ* is used to search for the standard model Higgs boson in the Hννmacr; and the Hℓ+ℓ- channels. The data sample corresponds to about 4.5 million hadronic Z decays collected by the ALEPH experiment at LEP from 1989 to 1995 at centre-of-mass energies at and around the Z peak. Three candidate events are found in the Hμ+μ- channel, in agreement with the expected background from the electroweak process e+e- ℓ+ℓ-qq̄. This search results in a 95% C.L. lower limit on the Higgs boson mass of 63.9 GeV/c2.
