Scientific paper

Generation of T-odd single spin asymmetries (SSA) by the various ingredients of QCD factorization is discussed. The possible use of SSA in studies of Generalized Parton Distribution (GPD) at HERA with the polarized lepton beam is suggested. The role of GPD in the investigation of orbital angular momenta of partons is discussed. The generalization of Equivalence principle, leading to the equipartition of momenta and total angular momenta, violated in perturbation theory, but possibly restored due to confinement and chiral symmetry breaking, is proposed. The T-odd fragmentation and fracture function are considered. The T-odd distribution (Sivers) function may be only effective, due to the imaginary cuts in the SIDIS and Drell-Yan process, while the existence of such universal functions should lead, after the integration over transverse momentum, to the strong T violation in polarized DIS.
