Description
I will present the transverse single spin asymmetries for very forward neutrons in polarized p-A ultra-peripheral collisions. These asymmetries are about 35 % and the cross section of p-Au ultra-peripheral collisions is comparable with that of hadronic interactions. Thus such asymmetries are central to the AN for very forward neutrons measured by the PHENIX zero-degree calorimeters (ZDCs) in high-energy polarized proton–nucleus (p–A) collisions at RHIC.
In this talk, I will present that the Monte Carlo simulation results involving both ultra-peripheral collisions and hadronic interactions can successfully reproduce the PHENIX measurements.
