在彩色玻璃凝聚体的框架下，研究了线偏振胶子在大原子核中的分布。我们发现，Weizsacker-Williams分布在大的横向动量时饱和了正性界限，而在小的横向动量时抑制了正性界限，而偶极分布则饱和了任意横动量的界限。我们还讨论了两种线偏振胶子分布都可以探测到的过程。
The distribution of linearly polarized gluons inside a large nucleus is studied in the framework of the color glass condensate. We find that the Weizsacker-Williams distribution saturates the positivity bound at large transverse momenta and is suppressed at small transverse momenta, whereas the dipole distribution saturates the bound for any value of the transverse momentum. We also discuss processes in which both distributions of linearly polarized gluons can be probed.
