Search for the Standard Model Higgs boson at the LEP2 collider near $\sqrt{s}$ = 183 GeV (1998)

Abstract
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.
