Single spin asymmetries in inclusive $π^{0}$ production in $p + p$ and $π^{-} + p$ interactions at 40-70 GeV

arXiv:hep-ex/0612039

Abstract

We present recent results of single-spin asymmetry $A_{N}$ measurements in $π^{0}$ 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.
