JAM小- $x$螺旋度现象学
JAM small-$x$ helicity phenomenology
摘要：
我们首次用第一性原理QCD导出的$x$的演化方程描述了小Bjorken $x$的$g_1^{p,n}$结构函数的世界数据。这是JAM全球框架内的蒙特卡罗分析，使我们能够拟合$x<0.1$以下的所有现有极化DIS数据，并预测EIC处小$x$ $g_1^{p,n}$的未来测量。这是确定夸克螺旋度PDF以及最终确定夸克对质子自旋的贡献的必要步骤。
英文摘要：
We present the first-ever description the world data on the $g_1^{p,n}$ structure function at small Bjorken $x$ using evolution equations in $x$ derived from first principles QCD. This is a Monte-Carlo analysis within the JAM global framework that allows us to fit all existing polarized DIS data below $x<0.1$ as well as predict future measurements of small $x$ $g_1^{p,n}$ at the EIC. This is a necessary step in determining the quark helicity PDFs and, ultimately, the quark contribution to the proton spin.
