Abstract.Upper limits on the cross-section of the pair-production process $${\ensuremath{{\mathrm{e}}^ + {\mathrm{e}}^-}} \to \mathrm{h}^0 \mathrm{A}^0$$, assuming 100 $$\%$$ branching fraction to hadrons, are derived from a new search for the $$\mathrm{h}^0\mathrm{A}^0 \to $$ hadrons final state, independently of the hadronic flavour of the decay products. This study, combined with previously published searches for the neutral Higgs bosons h0 and A0, is used to constrain the Type II Two Higgs Doublet Model (2HDM(II)) with no CP violation in the Higgs sector and no additional non-Standard Model particles besides the five Higgs bosons. The analy..
