T-odd quark distributions: QCD versus chiral models
arXiv:hep-ph/0212027
Abstract
The T-odd quark distrbutions are shown to vanish in the chiral sigma model in contrast to the opposite widespread opinion. This failure of the chiral sigma model is a feature of the model itself and has nothing to do with the recent progress in the clarification of the status of the T-odd distributions in QCD.
