Abstract

We show how the transverse tau tau spin correlations can be used to measure the parity of the Higgs boson and hence to distinguish a CP-even H boson from CP-odd A in the future high energy accelerator experiments. We investigate the subsequent decays of the tau into pi nu and rho nu. The prospects for the measurement of the Higgs boson parity with a mass of 120 GeV are quantified for the case of e+ e- collisions of 500 GeV center of mass energy. The Standard Model Higgsstrahlung production process is used as an example.
