Abstract

A search for neutral Higgs boson production in e+e- collisions using data collected by the ALEPH detector at the LEP accelerator is presented. Approximately 413 pb-1 of data collected at centre of mass energies between 188.6 and 201.6 GeV during 1998 and 1999 is used. The selection of candidates is described and the results of the search are presented and interpreted. Particular attention is given to the selection of the final states with four hadronic jets. No evidence of Higgs boson production is found. In the context of the Standard Model the lower limit on the Higgs boson mass is set at 105.2 GeV/c2 at the 95% confidence level.
