We use a dynamical model to evaluate these quantities in terms of HERMES kinematics. We point out how the measurements of cos(2phi) asymmetry may indicate the presence of T-odd structures in unpolarized ep scattering.10 pages, 5 figures, on the basis of the talks delivered by K.O. at DIS2003, XI International Workshop on Deep Inelastic Scattering, St. Petersburg, 23-27 April, 2003High Energy Physics - Phenomenologytext
