Abstract
The reaction e(+)e(-) --> HZ is used to search for the Standard Model Higgs boson, The data sample consists of integrated luminosities of 10 .9 pb(-1), 1.1 pb(-1), and 9.5 pb(-1) collected by the ALEPH experimen t at LEP during 1996, at centre-of-mass energies of 161, 170 and 172 G eV, respectively. No candidate events were found, in agreement with th e expected background of 0.84 events from all Standard Model processes . This search results in a 95% C.L. lower limit on the Higgs boson mas s of 69.4 GeV/c(2). When combined with earlier ALEPH searches performe d at energies at and around the Z peak, this limit increases to 70.7 G eV/c(2). (C) 1997 Elsevier Science B.V.
