这份报告给出了未来5年的RHIC自旋计划。所提出的程序将大大促进我们对质子自旋结构的理解。质子胶子极化的理解有望取得重大进展，W玻色子奇偶性违反测量将极大地影响我们对质子中反上和反下夸克极化的详细理解，而t横向自旋程序将进入研究与轨道角动量和夸克横向相关的不对称性的精确阶段。整个计划取决于跑步。该计划假定每年平均有10个星期。持续运行是必要的，以建立所需的峰值和平均光度增益，建立预期的极化水平，并积累实验所记录的所需的综合光度，在√s = 200 GeV和√s = 500 GeV下，到2013年。支持更高质子-质子发光的发展对于2013年以后的激动人心的计划是非常重要的。RHIC Spin Collaboration和PHENIX and STAR Collaboration的编剧：Gerry Bunce（主席）、Alexander Bazilevsky、Les Bland、Abha y Deshpande、Wolfram Fischer、Carl Gagliardi、Yuji Goto、Matthias Grosse-Perdekamp、Yousef M akdisi、Pavel Nadolsky、Thomas Roser、Ralf Seidl、Jim Sowinski、Marco Stratmann、Bernd Sur row、Werner Vogelsang、Feng Yuan
This report gives a RHIC spin plan for the next 5 years. The pro posed program would significantly advance our understanding of the spin structure o f the proton. Major advances are expected toward an understanding of the gluon polarization in the proton, the W boson parityviolating measurements would greatly impact our detailed u n erstanding of particularly the antiup and anti-down quark polarizations in the proton, and the t ransverse spin program will enter a precision stage studying asymmetries connected to orbita l angular momentum and to quark transversity. The entire plan rests on running. The plan assumes an average of ten weeks per year. Sustained running is necessary to build the required peak and av erage luminosity gains anticipated, to build the level of polarization anticipated, and to accum ulate the required integrated luminosity recorded by the experiments, both at √ s = 200 GeV and at √ s = 500 GeV, through 2013. Support for development of higher proton-proton luminosit y is very important for the exciting program envisioned for beyond 2013.
