Combined CDF and D0 upper limits on MSSM Higgs boson production in tau-tau final states with up to 2.2 fb-1

Combined results are presented on the search for a neutral Higgs boson in the di-tau final state using 1.8 fb{sup -1} and 2.2 fb{sup -1} of integrated luminosity collected at the CDF and D0 experiments respectively. Data were collected in p{bar p} collisions at a centre of mass energy of 1.96 TeV during RunII of the Tevatron. Limits are set on the cross section x branching ratio ranging from 13.6 pb to 0.653 pb for Higgs masses from 90 GeV to 200 GeV respectively. The results are then interpreted as limits in four different benchmark scenarios within the framework of the MSSM.
