论文摘要
我们研究了在大型强子对撞机上使用ftemtsoscic低摩肌相关测量的前景来访问J/PSI-Nucleon相互作用的性质。 QCD多极的扩展根据J/PSI的铬极化性，将正向散射幅度与关键基质元件相关联与核子质量问题的起源（核子中的平均染色体Gluon分布）。我们使用有关晶格QCD模拟和现象学模型提供的J/PSI核电相互作用的信息来计算J/PSI-Nucleon相关函数。计算的相关函数对相互作用表现出明显的敏感性，尤其是对J/PSI色彩极化性的敏感性。
We study the prospects of using femtoscopic low-momentum correlation measurements at the Large Hadron Collider to access properties of the J/psi-nucleon interaction. The QCD multipole expansion in terms of the J/psi chromopolarizability relates the forward scattering amplitude to a key matrix element to the origin of the nucleon mass problem, the average chromoelectric gluon distribution in the nucleon. We use information on the J/psi-nucleon interaction provided by lattice QCD simulations and phenomenological models to compute J/psi-nucleon correlation functions. The computed correlation functions show clear sensitivity to the interaction, in particular to the J/psi chromopolarizability.
