AI中文摘要：
我们证明，深度非弹性散射（DIS）中产生的量子关联层级可作为探测质子非微扰结构的新工具。具体而言，量子纠缠、量子失谐、量子导引和量子魔性对核子部分子分布函数（PDFs）具有非平凡且互补的敏感性，尤其对编码相互作用夸克横自旋极化的PDFs。这种关联为探测质子的部分子级张量电荷提供了独特手段，对超出标准模型（BSM）的物理搜索具有重要意义。我们还提出，如何将量子信息度量用于未来电子离子对撞机（EIC）等DIS实验中强子结构的精确研究。
英文摘要：
We show that the hierarchy of quantum correlations produced in deep-inelastic scattering (DIS) can serve as a novel probe of the proton's nonperturbative structure. Specifically, we show that quantum entanglement, discord, steering, and magic provide nontrivial and complementary sensitivities to the nucleon's parton distribution functions (PDFs), particularly those encoding the transverse-spin polarization of the interacting quark. This connection leads to a unique probe of the proton's parton-level tensor charges with implications for beyond Standard Model (BSM) physics searches. We propose how quantum information measures can be utilized for precision studies of hadron structure at DIS experiments like the upcoming Electron-Ion Collider (EIC).
