论文摘要
在这项工作中，我们分析了深度非弹性散射质子和核的纠缠熵。它是根据形式主义计算得出的，在形式主义中，小X处的党状态与质子构成的质子是由大量的微晶体所构成的，这些微晶体具有相等的概率。我们考虑从QCD颜色偶极偶极子图片中的偶极 - 靶标振幅的Gluon饱和模型获得的胶体数量N_ {gluon}的分析表达式。特别是，研究了每个核子的核纠缠熵。我们还研究了这些计算的潜在不确定性，并将结果与文献中的类似研究进行了比较。
In this work we analyse the entanglement entropy in deep inelastic scattering off protons and nuclei. It is computed based on the formalism where the partonic state at small-x is maximally entangled with proton being constituted by large number of microstates occuring with equal probabilities. We consider analytical expressions for the number of gluons, N_{gluon}, obtained from gluon saturation models for the dipole-target amplitudes within the QCD color dipole picture. In particular, the nuclear entanglement entropy per nucleon is studied. We also study the underlying uncertainties on these calculations and compare the results to similar investigations in literature.
