| Popis: | The single-spin asymmetry A N in the reaction π − + d ↑ → π 0 + X in the beam-fragmentation region at the energy of 40 GeV was investigated by using the PROZA setup installed at the U-70 accelerator of the Institute for High Energy Physics (IHEP, Protvino). It was measured to be A N = (13.6 ± 2.6(stat.) ± 2.0(syst.))% in the intervals 0.7 1.2 GeV/c. |
