  We discuss various azimuthal asymmetries in semi-inclusive DIS and e^+e^- ==>
h1 h2 X which involve chiral odd quantities like the transversity distribution
h_1 and a fragmentation function H_1^\perp. For the fragmentation described by
H_1^\perp azimuthal angular dependence has to be measured, but no polarization
vector of a final state hadron. We present first results on asymmetries
including the electroweak currents in one-hadron inclusive DIS.
