本文研究了RHIC中pp碰撞中两个几乎“背靠背”产生的喷流的方位角关联中的单横自旋不对称性。我们适当地考虑到初始和最终状态的部分子，可以产生这种不对称性QCD硬散射的相互作用。使用分布函数拟合到现有的单自旋数据，我们预测各种加权单自旋不对称的双喷流的相关性，现在很容易在RHIC测试。2007年美国物理学会。
We present a phenomenological study of the single-transverse spin asymmetry in azimuthal correlations of two jets produced nearly "back-to-back" in pp collisions at RHIC. We properly take into account the initial- and final-state interactions of partons that can generate this asymmetry in QCD hard-scattering. Using distribution functions fitted to the existing single-spin data, we make predictions for various weighted single-spin asymmetries in dijet correlations that are now readily testable at RHIC. © 2007 The American Physical Society.
