Abstract

We present recent results of single-spin asymmetry A_N measurements in π⁰ inclusive production. Asymmetry was measured in π^-p and pp interactions at 40 and 70 GeV correspondingly. Significant asymmetry was observed in the polarized target fragmentation region. The results are in agreement with "universal threshold" of single-spin asymmetry.
