On the feasibility of measuring transverse spin effects in τ+τ− production

In this paper we study experimental and theoretical aspects of the transverse spin polarization effects in τ+τ− production at LEP-I and at 10 GeV centre-of-mass energies. For this purpose QED and experimental cut-off effects have to be studied simultaneously and therefore a Monte Carlo technique is used. We present a method calculating the size of missing transverse spin effects in KORALZ and missing higher-order QED corrections in KORALB. Our aim is to determine the size of the related uncertainties for the two programs. Later, we discuss a transverse spin dependent observable and we show that with present statistics and systematics it can be measured at LEP. As an example of an experimental set-up we use the properties of the ALEPH detector. We discuss effects of the radiative corrections for our transverse spin correlation observable and for the visible total cross section.
