 Search for an invisibly decaying Higgs boson in $e^{+}e^{-}$ collisions at 189 GeV
 ALEPH Collaboration(s)
 (1999)
 The data collected in 1998 by ALEPH at LEP at a centre-of-mass energy of 188.6 GeV, corresponding to an integrated luminosity of 176.2 pb-1, are analysed to search for invisible decays of a Higgs boson produced in the reaction e+e- -> hZ. The number of events found in the data and their properties are in agreement with the Standard Model expectation. This search results in an improved 95% C.L. lower limit on the Higgs boson mass of 95.4 GeV/c2, assuming it decays totally invisibly and for a production cross section equal to that of the Standard Model.
