A search for pair produced charged Higgs bosons has been performed in the high energy data collected by DELPHI at LEP with View the MathML source, 172 and 183 GeV. The analysis uses the τντν, View the MathML source and View the MathML source final states and a combination of event shape variables, di-jet masses and jet flavour tagging for the separation of a possible signal from the dominant W+W− and QCD backgrounds. The number of selected events has been found to be compatible with the expected background. The lower excluded value of the H± mass obtained by varying the H±→ hadrons decay branching ratio has been found to be 56.3 GeV/c2.
