Abstract
We present a very promising method for a measurement of the Higgs boson parity using the H/A {yields} {tau}{sup +}{tau}{sup -} {yields} {rho}{sup +}{bar {nu}}{sub {tau}}{rho}{sup -}{nu}{sub {tau}} {yields} {pi}{sup +}{pi}{sup 0} {bar {nu}}{sub {tau}} {pi}{sup -}{pi}{sup 0} {nu}{sub {tau}} decay chain. The method is both model independent and independent of the Higgs production mechanism. Angular distributions of the {tau} decay products which are sensitive to the Higgs boson parity are defined and are found to be measurable using typical properties of a future detector for an e{sup +}e{sup -} linear collider. The prospects for the measurement of the parity of a Higgs boson with a mass of 120 GeV are quantified for the case of e{sup +}e{sup -} collisions of 500 GeV center of mass energy with an integrated luminosity of 500fb{sup -1}. The Standard Model Higgsstrahlung production process is used as an example.
