Single Spin Asymmetry of Charged Hadron Production by 40 Gev/C Polarized Protons

The single spin asymmetry for charge hadron production off nuclei (C, Cu) has been measured using 40 GeV/c polarized proton beam. The measurements were carried out using FODS-2 experimental setup at IHEP. The data are presented in the central region and the forward region with respect to the incident protons.
