In this work, the entanglement entropy is examined within the context of deep inelastic scattering in collisions. The calculation is based on a formalism where the partonic state at small- is maximally entangled, consisting of a large number of micro-states occurring with equal probabilities. Analytical expressions for the number of gluons, , are considered, derived from gluon saturation models for dipole-target amplitudes within the framework of the Quantum Chromodynamics (QCD) color dipole picture. A comparison of the entanglement entropy with thermodynamic entropy measured in and collisions at high energies is done.

研究 Gluon 饱和方法中低 Bjorken-x 下的部分纠缠熵

在这项工作中，在深度非弹性散射的背景下检查了纠缠熵碰撞。该计算基于一种形式主义，其中小分子态是最大纠缠的，由大量以相同概率出现的微观状态组成。胶子数量的解析表达式，，被认为是从量子色动力学（QCD）彩色偶极子图框架内的偶极子目标振幅的胶子饱和模型导出的。纠缠熵与热力学熵的比较和高能碰撞完成。
