统计部分子分布方法中胶子极化有多大?

How large is the gluon polarization in the statistical parton distributions approach?

Jacques Soffer, Claude Bourrely, Franco Buccella

摘要:

我们回顾了部分子分布的量子统计方法的理论基础,我们表明,通过使用一些最近的实验结果从深度非弹性散射,我们能够提高描述的数据通过一个新的部分子分布的测定。我们将看到一个大的胶子极化出现,对质子自旋有重要的贡献。

英文摘要:

We review the theoretical foundations of the quantum statistical approach to parton distributions and we show that by using some recent experimental results from Deep Inelastic Scattering, we are able to improve the description of the data by means of a new determination of the parton distributions. We will see that a large gluon polarization emerges, giving a significant contribution to the proton spin.
