Abstract

During 1997 the ALEPH experiment at LEP gathered of data at centre-of-mass energies near . These data are used to look for possible signals from the production of the Standard Model Higgs boson in the reaction e+e−→HZ. No evidence of a signal is found in the data; seven events are selected, in agreement with the expectation of 7.2 events from background processes. This observation results in an improved lower limit on the mass of the Higgs boson: at 95% confidence level.
