R. Barate et al., Searches for neutral Higgs bosons in e(+)e(-) collisions at centre-of-massenergies from 192 to 202 GeV, PHYS LETT B, 499(1-2), 2001, pp. 53-66
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 energie
s 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 sign
al 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 bos
ons h and A, respectively. For a Higgs boson decaying invisibly and produce
d with the Standard Model cross section, masses below 106.4 GeV/c(2) are ex
cluded. (C) 2001 Published by Elsevier Science B.V.
