Search for the Standard Model Higgs boson at the LEP2 collider near s\sqrt{s} = 183 GeV

During 1997 the ALEPH experiment at LEP gathered 57 \pb of data at centre-of-mass energies near 183 ~\G. These data are used to look for possible signals from the production of the Standard Model Higgs boson in the reaction \ee\r\H\Z. 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: \mH > 87.9 \Gcs at 95\% confidence level.
