标题： Femtoscopy of the Origin of the Nucleon Mass

摘要： 我们研究在大型强子对撞机上使用飞秒学低动量相关测量来探索J/psi-核子相互作用的性质。 以J/psi色极化率形式的QCD多极展开将正向散射振幅与核子质量问题的起源——核子中平均色电胶子分布的关键矩阵元联系起来。 我们利用来自格点QCD模拟和现象学模型的J/psi-核子相互作用信息来计算J/psi-核子相关函数。 计算的相关函数显示出对相互作用的明显敏感性，特别是对J/psi色极化率的敏感性。 显示英文摘要

摘要： 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.
