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

Partial wave analysis and evaluation of resonance polarization in 3pi production in pi Be collisions at 37-GeV/c

A large correlation of production and decay planes of the π−π+π− system in dissociation of a 40-GeV/c π− beam on nuclear targets was observed. The dependence of the correlation on atomic number, Feynman variable, and transversal momentum, as well as on invariant mass of the pion triple and neutral pion pair, was investigated. It was shown that the phenomenon has a clear dynamical origin and resembles the single-spin asymmetry behavior.A large correlation of production and decay planes of (\pi^-\pi^+\pi^-)-system in dissociation of
