On the T-odd quark fragmentation function and on transversal handedness

The first probe of the correlation of the T-odd one-particle fragmentation function responsible for the left-right asymmetry of fragmentation of a transversely polarized quark is done by using the 1991-95 DELPHI data for Z to 2-jet decay. Integrated over the fraction of longitudinal and transversal...

description The first probe of the correlation of the T-odd one-particle fragmentation function responsible for the left-right asymmetry of fragmentation of a transversely polarized quark is done by using the 1991-95 DELPHI data for Z to 2-jet decay. Integrated over the fraction of longitudinal and transversal momenta, this correlation is of 1.5554330rder, which means order of 13 0.000000or the analyzing power. A rather large ( approximately=10) handedness transversal to the production plane was observed in the diffractive production of ( pi /sup -/ pi /sup +/ pi /sup -/) triples from nuclei by the 40 GeV/c pi /sup -/-beam. It was shown that the phenomenon has a clear dynamic origin and resembles the single spin asymmetry behavior. All this makes us hope to use this effects in polarized DIS experiments for transversity measurement. (22 refs).
