# A search for invisible Higgs bosons produced in $e^{+} e^{-}$ interactions up to $\sqrt{s}$ = 189 GeV

Abstract : Searches for {\mbox{${\mathrm H} {\mathrm Z}$}} production d with the Higgs boson decaying into an invisible final state have been performedd the data collected by the DELPHI experimentd up to the centre-of-mass energy of 188.6~{\mbox{${\mathrm{GeV}}$}}. d The hadronic and muon pair final states of the d {\mbox{${\mathrm Z}$}} d boson were analysed. No signal was found. d Upper limits on the cross-section and the corresponding Higgs boson mass d limits were set d at 95\% confidence level. Combining these results with DELPHI results for the vd a 95\% confidence level Higgs mass lower limit of 92.3~{\mbox{$d {\mathrm{GeV}}$}} was obtained, independentd of the branching ratio into visible and invisible decays.
