Abstract

The single-spin asymmetry and hadron polarization data are analyzed in the framework of a phenomenological effective-color-field model. Global analysis of the single-spin effects in hadron production is performed for h+h, h+A, A+A and lepton+N interactions. The model explains the dependence of the data on xFx_{F}, pTp_{T}, collision energy s\sqrt{s} and atomic weights A1A_{1} and A2A_{2} of colliding nuclei. The predictions are given for not yet explored kinematical regions.
