The correlation between the longitudinal polarization of a fragmenting quark and the transverse momenta of the produced hadrons was predicted over two decades ago. Nevertheless, experimental searches in the electron-positron annihilation process, both through the so-called jet handedness measurement by the SLD collaboration and more recently via the helicity-dependent dihadron fragmentation function (DiFF) by the BELLE collaboration, did not yield a signal. In this talk, we will first explain the zero result at BELLE, and describe new method for accessing the helicity-dependent DiFF in the same experiment. We will also propose another measurement of the same DiFF in semi-inclusive deep inelastic scattering experiments.
