Microscopic Stern-Gerlach Effect and Thomas Spin Precession as an Origin of the SSA
Abramov, V. V.
Original · EN
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 xF, pₜ, collision energy √s and atomic weights A₁ and A₂ of colliding nuclei. The predictions are given for not yet explored kinematical regions.
