We demonstrate that a measurement of the impact parameter in one-prong taudecay can be useful for the determination of the Higgs boson parity in the H/A--> tau tau; tau --> rho nu decay chain. We have estimated that for a detectionset-up such as TESLA, use of the information from the tau impact parameter canimprove the significance of the measurement of the parity of the Standard Model120 GeV Higgs boson to 4.5 sigma, and in general by factor of about 1.5 withrespect to the method where this information is not used.  We also show that the variation in the assumption on the precision of themeasurement of the impact parameter and/or pi's momenta does not affect thesensitivity of the method. This is because the method remains limited by thetype of twofold ambiguity in reconstructing the tau momentum.Comment: 12 pages, 12 figures, LaTe
