摘要：

The first probe of the correlation of the T-odd one-particle fragmentation function which is responsible for the left-right asymmetry of fragmentation of transversely polarized quark and antiquark is done using the 1991-95 DELPHI data for Z --> 2 jet decay. Being integrated over the fraction of longitudinal and over transverse momentum, this correlation is of 2.5ppm order, that means order of 7% for the analyzing power. This gives a hope to use certain effects in polarized DIS experiments for transversity measurement.
