Abstract
We present the results of a search for Higgs bosons predicted in two-Higgs-doublet models, in the case
where the Higgs bosons decay to tau lepton pairs, using 1:8 fb[superscript -1] of integrated luminosity of pp[over-bar] collisions recorded by the CDF II experiment at the Fermilab Tevatron. Studying the mass distribution in events where one or both tau leptons decay leptonically, no evidence for a Higgs boson signal is observed. The
result is used to infer exclusion limits in the two-dimensional space of tan[beta] versus m[subscript A](the ratio of the
vacuum expectation values of the two Higgs doublets and the mass of the pseudoscalar boson, respectively).
