Searches for neutral Higgs bosons are performed with the 237 pb(-1) of data collected in 1999 by the ALEPH detector at LEP, for centre-of-mass energies between 191.6 and 201.6 GeV. These searches apply to Higgs bosons within the context of the Standard Model and its minimal supersymmetric extension (MSSM) as well as to invisibly decaying Higgs bosons. No evidence of a signal is seen. A lower limit on the mass of the Standard Model Higgs bosun of 107.7 GeV/c(2) at 95% confidence level is set. In the MSSM, lower limits of 91.2 and 91.6 GeV/c(2) are derived for the masses of the neutral Higgs bosons h and A, respectively. For a Higgs boson decaying invisibly and produced with the Standard Model cross section, masses below 106.4 GeV/c(2) are excluded. (C) 2001 Published by Elsevier Science B.V.

Abstract
Searches for neutral Higgs bosons are performed with the 237 pb(-1) of data collected in 1999 by the ALEPH detector at LEP, for centre-of-mass energies between 191.6 and 201.6 GeV. These searches apply to Higgs bosons within the context of the Standard Model and its minimal supersymmetric extension (MSSM) as well as to invisibly decaying Higgs bosons. No evidence of a signal is seen. A lower limit on the mass of the Standard Model Higgs bosun of 107.7 GeV/c(2) at 95% confidence level is set. In the MSSM, lower limits of 91.2 and 91.6 GeV/c(2) are derived for the masses of the neutral Higgs bosons h and A, respectively. For a Higgs boson decaying invisibly and produced with the Standard Model cross section, masses below 106.4 GeV/c(2) are excluded. (C) 2001 Published by Elsevier Science B.V.
