Relying on previous results, that link entanglement entropy and parton distribution functions in deep inelastic scattering, and focusing on the small Bjorken scaling region we present here indications that gluon shadowing might indeed be explained as due to a depletion of the entanglement entropy, between observed and unobserved degrees of freedom, per nucleon within a nucleus, with respect to the free nucleon. We apply to gluon shadowing the general Page approach to the calculation of the entanglement entropy in bipartite systems, giving physical motivations of the results.

胶子阴影和核纠缠熵

依赖于先前的结果，将纠缠熵和部分子分布函数联系起来在深度非弹性散射中，并关注我们在这里提出的小 Bjorken 尺度区域，这表明胶子阴影确实可以解释为由于纠缠熵的消耗，在观察到的和相对于自由核子，核内每个核子的未观察到的自由度。我们将通用 Page 方法应用于胶子阴影来计算二分系统中的纠缠熵，给出结果的物理动机。
