2015年，PHENIX合作测量了在200 GeV质心能量的横向极化质子-质子和质子-核碰撞中包含中子的非常向前（）的单自旋不对称性。该数据集的先前出版物集中在这种不对称性的核依赖性上。在这个测量中，包含的中子单自旋不对称性的质子-质子碰撞的显式横向动量依赖提取使用的横向动量的自举展开技术。这种明确的横向动量依赖性将有助于提高对产生这些不对称性的机制的理解。
In 2015, the PHENIX collaboration has measured very forward () single spin asymmetries of inclusive neutrons in transversely polarized proton-proton and proton-nucleus collisions at a center of mass energy of 200 GeV. A previous publication from this dataset concentrated on the nuclear dependence of such asymmetries. In this measurement the explicit transverse momentum dependence of inclusive neutron single spin asymmetries for proton-proton collisions is extracted using a bootstrapping unfolding technique on the transverse momenta. This explicit transverse momentum dependence will help improve the understanding of the mechanisms that create these asymmetries.
