Description

We show how the transverse τ+τ- 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 A0 in the future high energy accelerator experiments. We investigate the subsequent decay of the τ± into π±ντ(bar)(ντ) and ρ±ντ(bar)(ντ). 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. (author)
