Abstract

Single Spin Asymmetry ANA_N (SSA) was measured at the Protvino 70 GeV accelerator. Asymmetry in the reaction \ppdup\ppdup is close to zero within error bars at small \xf|\xf| and pT<1.5p_T<1.5 GeV/c. SSA in the reaction \pimp\pimp at polarized target fragmentation region equals to (13.8±3.8)(-13.8 \pm 3.8)% at xf>0.4|x_f|>0.4. There is an indication that the asymmetry begins to rise up at the same centre of mass system pion energy.
