Time-reversal-odd asymmetry in pion leptoproduction at HERMES
arXiv:hep-ph/9806420
Abstract
We estimate the size of the azimuthal asymmetry of the semi-inclusive pion production in the deep-inelastic scattering of a polarized lepton beam off an unpolarized nucleon target for the produced hadron, arising due to both nonperturbative and perturbative effects.
