Time-reversal-odd distribution functions in chiral models with vector mesons

The so-called time-reversal odd distribution functions are known to be nonvanishing in QCD due to the presence of the link operator in the definition of these quantities. I show that T-odd distributions can be nonvanishing also in chiral models, if vector mesons are introduced as dynamical gauge bosons of a hidden local symmetry. Moreover, since the flavor dependence of these distributions is different in chiral models respect to nonchiral ones, the phenomenological analysis of experimental data will be able to distinguish between these two classes of models.
