= 200 GeV=200GeVにおける偏極陽子-陽子および陽子-原子核衝突における前方中性子生成のシングルスピン非対称性Tanida, Kiyoshi; PHENIX Collaboration*
In high-energy hadron collisions, most energy goes to the forward region. However, particle production mechanisms in the forward region are not well understood as perturbative QCD is not applicable at small momentum transfers. We study single spin asymmetries (
) of forward neutron production in the PHENIX experiment using a transversely polarized proton beam. In 2015, we took data for + A collisions for the first time with Au and Al beams at = 200 GeV and observed a surprising A dependence. The results are presented together with discussions on possible mechanisms that could explain them.
