Description
In high-energy hadron collisions, most energy goes into 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 (A_N) of forward neutron production
in the PHENIX experiment using a transversely polarized proton beam.
In 2015, we took data for p + A collisions for the first time with
Au and Al beams at sqrt(s_NN)= 200 GeV and observed a surprising A dependence.
The results will be presented in the conference together with discussions
on possible mechanisms that could explain the A_N results of
forward neutron production.
