Measurement of the transverse spin correlations in the $\tau^+ \tau^-$ production
The first measurement of the transverse-transverse and transverse-normal $\tau^+\tau^-$ spin correlations in the $e^+e^- \rightarrow \tau^+\tau^-$ reaction at the $Z^0$ peak is presented. Based on the data taken by ALEPH during 1992, 1993 and 1994, the results are: A_{TT} = 0.99 +- 0.13 (stat.) +- 0...
