Measurement of the transverse spin correlation in the decay $Z^0 \to \tau^{+} \tau^{-}$
The measurement of the correlation between the transverse spin components of $\tau^+\tau^-$ pairs collected during 1992 to 1994 with the DELPHI detector at LEP1 is presented. A value \begin{center} $C_{TT}$~=~0.87~$\pm$~0.20~(stat.)~$^{+~0.10}_{-~0.12}$~(syst.) \end{center} was obtained for the corr...
