Abstract

Single Spin Asymmetries (SSA) AN measured in the two reactions at the Protvino 70 GeV accelerator are presented. AN in the reaction p+p→π0+X  in the central region is close to zero within the error bars. SSA in the reaction π-+p→π0+X in the polarized target fragmentation region is equal to (-154)% at |xF|>0.4. There is an indication that the asymmetry arises at the same pion energy in the center of mass system.
