Abstract
Searches for neutral Higgs bosons in the Standard Model and the MSSM
have been performed using data collected by the DELPHI experiment at a
centre-of-mass energy of 188.7 GeV, corresponding to
an integrated luminosity of 158 pb-1.
These analyses are used, in combination with our results from lower
energies, to set new 95% confidence level lower mass bounds on the
Standard Model Higgs boson (94.6 GeV/c2) and on the lightest neutral
scalar (82.6 GeV/c2) and neutral pseudoscalar (84.1 GeV/c2) Higgs
bosons in a representative scan of the MSSM parameters. The results are also
interpreted in the framework of a general two-Higgs doublet model.
