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

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/120042We 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.4 pages, 9 figures, Talk given at ICHEP-2006High Energy Physics - ExperimentSingle spin asymmetries in inclusive $π^0$ production in $p+p$ and $π^-+p$ interactions at 40-70 GeVtext
