Search for MSSM Higgs Boson Production in Di-tau Final States with L=2.2 fb^-1 at the DO Detector

A search for the production of neutral Higgs bosons decaying into tau anti-tau final states is presented in p-pbar collisions at a center-of-mass energy of 1.96 TeV. The integrated luminosity used for the study is about 2.2 fb^-1, collected by the DO Experiment at the Fermilab Tevatron Collider. No significant excess is observed over the background expectation. The results are interpreted in the Minimal Supersymmetric Standard Model (MSSM) and regions in the mA, tan(beta) parameter space for two MSSM benchmark scenarios are excluded.
