Abstract:
A search for the direct production of Higgs bosons in the di-tau decay mode is performed with 86.3卤3.5pb-1 of data collected with the Collider Detector at Fermilab during the 1994-1995 data taking period of the Tevatron. We search for events where one tau decays to an electron plus neutrinos and the other tau decays hadronically. We perform a counting experiment and set limits on the cross section for supersymmetric Higgs boson production where tan 尾 is large and mA is small. For a benchmark parameter space point where mA0=100GeV/c2 and tan 尾=50, we limit the production cross section multiplied by the branching ratio to be less than 77.9 pb at the 95% confidence level compared to the theoretically predicted value of 11.0 pb. This is the first search for Higgs bosons decaying to tau pairs at a hadron collider. 漏 2005 The American Physical Society.
